Technical field
The present invention relates to be suitable as usefulness insulating material such as printed-wiring board (PWB) heat-resistant polyphenylene ether (to call PPE in the following text) resin combination, use the prepreg of this PPE resin combination and use the veneer sheet of this prepreg.
Background technology
In recent years, development along with integrated technology, joining technique and the mounting technology of the semiconducter device of using in electronics, high-density electronic package and the high density printed circuit board wiring, electronics has obtained continuous progress, and especially using on the electronics in broadbands such as the mobile communications device at those has had alarming development.
Printed-wiring board (PWB), it is as a formation of this electronics, towards the multilayer board wiring development of more accurate pitch simultaneously of higher degree.For signaling rate being brought up to the needed level of information processing of quickening, effectively way is to reduce the specific inductivity of institute's materials used, and in order to reduce transmission loss, effectively way is to use the material than the low-dielectric loss factor (dielectric loss).
Therefore, the PPE resin is the material that is suitable for the printed-wiring board (PWB) in the electronics that uses the broadband, because the PPE resin has good high frequency characteristics (dielectric characteristics), as specific inductivity, dielectric loss etc.Yet the PPE resin does not still possess sufficiently high thermotolerance and dimensional stability.In addition, a shortcoming of PPE resin is that it has high-melting-point usually, use this PPE resin to be used to produce common multilayer printed circuit board often causes the prepreg melt viscosity with prepreg increase, cause in the multi-ply wood production process manufacturing deficiency such as hole and scratch take place, cause the multi-ply wood quality of being supplied reliable inadequately.
The open communique of Japanese Patent is put down into and has been disclosed a kind of be intended to improve the PPE resin combination of thermotolerance and dimensional stability, the veneer sheet that uses the prepreg of this PPE resin combination and use this prepreg for 8-231847 number.They are respectively to contain PPE, triallyl isocyanurate and inert through the PPE of the compound of bromination resin combination; Use the prepreg of this PPE resin combination; With the veneer sheet that uses this prepreg.
Yet, when using the open communique of Japanese Patent to put down into 8-231847 number described resin combination, be difficult to produce multi-ply wood, be because the fusing point height of this PPE resin itself, under common hot pressing temperature, the melt viscosity of this resin combination is too high so that interior condactive pattern layer can not be inserted in the multilayer printed circuit board.
In addition, Japanese Patent is open have been proposed for communique 2002-265777 number a kind ofly to contain than the PPE of small molecular weight thereby have the PPE resin combination that molten resin preferably flows property and have better processing characteristics under common hot pressing temperature in the course of processing, uses the prepreg of this PPE resin combination and uses the veneer sheet of this prepreg.This PPE resin combination is effective in and improves multiple-plate production efficiency.
Also have United States Patent (USP) the 6th, 352, the PPE that discloses its terminal hydroxyl by the represented group end capping of following formula No. 782.Although in the embodiment molecular weight of employed PPE is clearly described at all, the number-average molecular weight of this PPE is described to be had preferably less than 10,000, especially in approximately from 300 to 5,000 (further preferably approximately from 500 to 5,000).
Figure G2009101673192D00021
As mentioned above, for improve fusion PPE resin flow and thereby improve the production efficiency of prepreg, effectively way is to reduce the molecular weight of PPE.
Yet, the problem that the thermotolerance of the resulting veneer sheet of reduction simultaneous of PPE molecular weight descends.Though can prevent to fall stable on heating decline, can cause the reduction of the relative content of the PPE with outstanding dielectric characteristics simultaneously again, the feasible product that is difficult to produce than low-k by the amount that increases crosslinking and curing agent, triallyl isocyanurate.Incidentally, for using for the above-mentioned Japanese Patent veneer sheet that openly composition of communique 2002-265777 number description makes, then specific inductivity is 3.5 to 3.7 (1MHz) when combining with E type woven fiber glass, and then specific inductivity is 3.3 to 3.5 (1MHz) when combining with NE type woven fiber glass.
Plant situation for this reason, the product that need have low-k more is to deal with the sharp increase of the information processing capacity in broadband device in recent years.
Summary of the invention
The present invention considers under the above-mentioned situation and finishes, the purpose of this invention is to provide and a kind ofly used low-molecular-weight PPE but still keep good dielectric characteristics and the polyphenyl ether resin composition of veneer sheet oblatio high heat resistance, and the prepreg that uses this polyphenyl ether resin composition.Another object of the present invention provides a kind of have simultaneously excellent dielectric characteristics and stable on heating veneer sheet.
In order to address the above problem, the inventor has carried out a large amount of research by synthetic various PPE to the structure and the relation between the dielectric characteristics of these materials.Found that, use a kind of special group that the PPE terminal hydroxyl is made amendment and to improve reaction efficiency between PPE and the crosslinking and curing agent, even for the purpose that increases the flowability under its molten state, when using lower molecular weight PPE, also can make dielectric characteristics good, have higher glass transition temperature, do not damage the PPE resin combination of PPE natural characteristics again.Use this PPE resin combination can produce colory prepreg and veneer sheet.
That is, polyphenyl ether resin composition according to the present invention is the composition that comprises polyphenylene oxide and crosslinking and curing agent, wherein, described polyphenylene oxide by following formula (0) expression and its number-average molecular weight in 1,000 to 7,000 scope.

Polyphenyl ether resin composition of the present invention for example is the composition that comprises polyphenylene oxide and crosslinking and curing agent, and wherein, described polyphenylene oxide is by following formula (I) expression, and its number-average molecular weight is in 1,000 to 7,000 scope,
Figure G2009101673192D00032
In the formula (I), X is an aryl; (Y) mIt is the polyphenylene oxide part; R 1To R 3Be hydrogen atom, alkyl, alkenyl or alkynyl independently of one another; N is 1 to 6 integer; Q is 1 to 4 integer.
" aryl " of the present invention is meant aromatic hydrocarbon group.These aryl comprise, for example phenyl, xenyl, indenyl and naphthyl, and aryl phenyl preferably.In addition, the group that a plurality of aryl are bonded together, for example, those be situated between by oxygen be bonded to as the hexichol ether etc.; Those are situated between by ketonic linkage synthetic such as benzophenone base etc.; And those be situated between by alkylene base (alkylene group) be bonded to as 2,2-diphenyl propane bases etc. are included in the defined aryl of the present invention.And these aryl can be further replace by one or more substituting groups, for example alkyl (preferred C 1-C 6Alkyl; Especially methyl), thiazolinyl, alkynyl, halogen atom or other common substituting group.Because aryl is to be situated between to be bonded to the polyphenylene oxide part by Sauerstoffatom, therefore substituent upper limit number depends on the number of polyphenylene oxide part.
Should " polyphenylene oxide part " be made of multiple phenoxy group unit, its phenyl can be replaced by common substituting group.Such polyphenylene oxide partly comprises, for example, and by the compound of following formula (II) expression.
Figure G2009101673192D00041
[in the formula (II), R 4To R 7Be respectively hydrogen atom, alkyl, thiazolinyl, alkynyl or alkene carbonyl independently; M is 1 to 100 integer.]
Here; the unsaturated alkyl that contains as polyphenylene oxide side chain appearance partly; for example vinyl, 2-propenyl (allyl group), methacryloyl, acryl, 2-propynyl groups such as (propargyls) can further improve the effect and the effect of crosslinking and curing agent effectively.
Here, m should adjust to and make the number-average molecular weight of PPE (0) drop in 1,000 to 7,000 the scope.
Should " alkyl " be meant the stable hydrocarbon group, be preferably C 1-C 10Alkyl, more preferably C 1-C 6Alkyl, more preferably C 1-C 4Alkyl most preferably is C 1-C 2Alkyl.Such alkyl for example comprises, methyl, ethyl, propyl group, sec.-propyl, butyl, isobutyl-, sec-butyl, the tertiary butyl, amyl group and hexyl.
Should " thiazolinyl " be meant the unsaturated hydrocarbon group that contains at least one carbon-to-carbon double bond in its structure, be preferably C 2-C 10Thiazolinyl, more preferably C 2-C 6Thiazolinyl most preferably is C 2-C 4Thiazolinyl.These thiazolinyls for example comprise, ethene, 1-propylene, 2-propylene, different propylene, butylene, iso-butylene, amylene and hexene.
Should " alkynyl " be meant the unsaturated hydrocarbon group that contains at least one carbon-to-carbon triple bond in its structure, be preferably C 2-C 10Alkynyl, more preferably C 2-C 6Alkynyl most preferably is C 2-C 4Alkynyl.These alkynyls for example comprise, acetylene, 1-propine, 2-propine, different propine, butine, isobutyl alkynes, pentyne and hexin.

In PPE (0), n is preferably 1 to 4 integer; More preferably 1 or 2; And most preferably be 1.In addition, q is preferably 1 to 3 integer; More preferably 1 or 2; And most preferably be 1.Though m can be 1 to 100 integer, because the number-average molecular weight of PPE of the present invention (0) should be 1,000 to 7,000 at least, so m should adjust according to the number-average molecular weight of desirable PPE (0).That is to say, though value according to m, the molecular weight of certain PPE (0) may be less than 1,000 or greater than 7,000, but the number-average molecular weight of the entire PP E (0) that is contained in the PPE resin combination of the present invention should be 1,000 to 7,000, so m needn't be certain definite value, and can in a certain scope, change.
In the lower part structure of PPE (0), preferred Z be penylene base and n be 1 group (promptly, the phenmethyl derivative), perhaps, Z is that Sauerstoffatom and n are 2 group, more preferably to Ethenylbenzene methyl (p-ethenybenzyl group), an Ethenylbenzene methyl (m-ethenybenzyl group) or oxidation of ethylene ethyl (ethenyloxyethyl group).
Figure G2009101673192D00051
Lower part at PPE (I) for example is at least a group that is selected from an Ethenylbenzene methyl and the Ethenylbenzene methyl.
Figure G2009101673192D00052
The PPE (0) that has these groups endways has good especially interaction with crosslinking and curing agent, and is not needing to add the product that can produce low-k under the situation of a large amount of crosslinking and curing agents.Especially, the PPE that has endways an Ethenylbenzene methyl and an Ethenylbenzene methyl both sides has low melting point and low softening point, and those PPE that only have endways the Ethenylbenzene methyl then have high-melting-point and high softening-point.Therefore, by adjusting fusing point and the softening temperature that to regulate PPE to the ratio of an Ethenylbenzene methyl and an Ethenylbenzene methyl arbitrarily.
The number-average molecular weight of PPE (0) is 1,000 to 7,000.This is because when using molecular weight to surpass 7, during 000 PPE, then mobile decline makes multilayer processing difficult more in the course of processing of PPE, and when using molecular weight less than 1, during 000 PPE, then resulting prepreg and veneer sheet not necessarily always present good dielectric characteristics of PPE resin inherent and thermotolerance.Be the PPE resin that manufacturing has good flowability, thermotolerance and dielectric characteristics, its number-average molecular weight is preferably 1,200 or bigger, and 5,000 or littler, more preferably 1,500 or bigger, 4,500 or littler.
In addition, when mixing, have PPE (0) and can greatly improve consistency with crosslinking and curing agent than small molecular weight with crosslinking and curing agent.That is to say that the molecular weight of PPE (0) is more little, the consistency between blending ingredients is just good more.Therefore, this low-molecular-weight PPE stops the viscosity that causes by being separated to become big, suppresses the volatilization of lower molecular weight crosslinking and curing agent, thereby has improved the resin filling perforation performance to internal through-hole (to call IVH in the following text) especially.Especially, PPE (0) is preferably 30/70 to 90/10 (mass parts) with the blending ratio of crosslinking and curing agent.That is, if the content of PPE (0) less than 30 mass parts, the veneer sheet that makes is frangible, and if the content of PPE (0) greater than 90 mass parts (content of crosslinking and curing agent is less than 10 mass parts), the thermotolerance of veneer sheet may descend.
The method of making PPE (0) below will be described.
So far, PPE, for example, by United States Patent (USP) the 4th, 059, No. 568 disclosed method is made, and its number-average molecular weight (Mn) is generally 13,000 to 25,000.Yet PPE institute inherent high resin fusing point and melt viscosity make the problem that occurs manufacturing deficiency as the material of multilayer printed circuit board the time.So, can reduce resin viscosity and improve processing characteristics by the molecular weight that reduces PPE.
According to the public table of Japanese Patent communique 2002-536476 number, lower molecular weight PPE can make in all sorts of ways and separate and obtain, and separates acquisition but adopt with the reagent coprecipitation that is fit to usually.As the method for the molecular weight that reduces PPE, can use the described method of organic chemistry magazine the 34th volume 297-303 page or leaf (1969).This method adopts the method for phenols and PPE reaction to reduce the molecular weight of PPE.The phenols that uses in this reaction comprise phenol, cresols, xylenol, Resorcinol, dihydroxyphenyl propane, 2,4,4 '-dihydroxy diphenyl ether etc., but preferred the use has 2 or more a plurality of functional phenols and improves thermotolerance after product solidifies.In addition, the initiator of reaction preferably uses oxygenant such as benzoyl peroxide, 3,3 ', 5,5 '-tetramethyl--1,4-hexichol oxygen quinone, chloranil, 2,4,6-three (tertiary butyl phenoxy group), single tert-butyl peroxy isopropyl carbonate and Diisopropyl azodicarboxylate also can add metal carboxylate if desired to promote reaction.In addition, the generation of reaction back more preferably increases to suppress specific inductivity as initiator as the compound of the volatile constituent of low-molecular-weight alcohol.
The reaction that is used to obtain lower molecular weight PPE is by joining high molecular PPE (number-average molecular weight surpasses 10,000 common PPE), phenols and initiator in the solvent and heating this mixture and finish.Cobalt naphthenates etc. can be used as catalyzer and are added in this mixture.The solvent that here uses is not particularly limited, as long as this solvent can dissolve these components to appropriateness and can disturbance reponse, it for example can be, aromatic solvent such as benzene, toluene etc. all can be used as solvent and use.Temperature of reaction and reaction times can decide according to number-average molecular weight of required PPE etc., and it for example can be, carries out under 60 to 100 ℃ 30 minutes to 6 hours.These reaction conditionss can be determined by preliminary experiment.After reaction finishes, in the reaction process below under decompression state, being directly used in the solvent distillation and with lower molecular weight PPE.Perhaps, can in reaction mixture, add the Weak solvent (as methyl alcohol) of PPE, and the needed PPE of postprecipitation, so that its thick purification.
The PPE that obtains by above-mentioned reaction has suitable low molecular weight because of the fracture of main polymer chain between the reaction period, and the one end has from used phenols derives and the aromatic yl group that comes, and the other end has the oh group that is expressed from the next.In the formula, the number q of the polyphenylene oxide of each phenols part depends on the number of hydroxyl in the used phenols.That is to say that when phenols had only a hydroxyl, then q was 1, when multivalence phenol during as phenols, then q is 2 or bigger.

[wherein, X, (Y) mSame as described above with the implication of q.]
Then, according to following reaction with the terminal hydroxyl group end-blocking.
Figure G2009101673192D00071
[wherein, X, (Y) m, Z, R 1To R 3, m, n and q implication same as described above; Hal represents chlorine atom or bromine atoms.]
In above-mentioned reaction, make under the PPE that obtains by the reaction of the above-mentioned reduction molecular weight situation that alkali exists in solvent with reaction such as halogenated compound such as 1-chloro-4-methyl-benzene the terminal hydroxyl group end-blocking.Alkali metal hydroxide as sodium hydroxide etc. can as described in alkali.In this case, join alkali such as aqueous sodium hydroxide solution with for example toluene etc. and be in the lower molecular weight PPE solution of solvent, quaternary ammonium salt (for example tetra-n-butyl ammonium bromide) can also be added wherein to promote reaction as phase-transfer catalyst again.Temperature of reaction and reaction times are depended on the kind of compound used therefor to a great extent, for example, and can be room temperature to 100 ℃ following reaction 30 minutes to 10 hours.After reaction finished, required product can obtain by following step: the Weak solvent by adding required product for example water, lower alcohol such as methyl alcohol etc. precipitates product, filter, and with identical solvent wash, and drying.
The PPE of the present invention of Huo Deing is owing to its lower molecular weight gives the PPE resin combination good flowability like this.In addition,, therefore use the PPE of the present invention of institute's allowance can improve the dielectric characteristics of resulting PPE resin combination, and keep the natural characteristics of this PPE such as thermotolerance etc. because this PPE can the very easy curing of enough less crosslinking and curing agents.
In addition, in PPE resin combination of the present invention,, can further improve the flowability control and the thermotolerance of PPE resin combination related to the present invention by being that 9,000 to 18,000 unmodified PPE is used in combination with above-mentioned PPE and number-average molecular weight.In addition, it can also composite inhibiting in the precipitation of additive component such as filler etc.Incidentally, this unmodified PPE is the polyphenylene oxide that does not contain unsaturated carbon-carbon-based group in the molecule, and its combined amount is preferably 3 to 70 mass parts with respect to the total amount of PPE and crosslinking and curing agent.
In addition, for improving thermotolerance, cohesiveness and dimensional stability, except that PPE, if desired, also can use at least one to be selected from following compatilizer: styrene-butadiene block copolymer, styrene-isoprene block copolymer, 1,2-polyhutadiene, 1, toxilic acid modified polybutadiene, acrylic acid modified polyhutadiene and epoxide modified polyhutadiene.
The crosslinking and curing agent that joins in the PPE resin combination of the present invention mainly is crosslinked on three-dimensional space to the polyphenylene oxide of the invention described above.Even add in the PPE resin combination in order to increase mobile low-molecular polyphenylene ether, crosslinking and curing agent still can keep the thermotolerance of PPE resin etc.The crosslinking and curing agent that has excellent compatibility with PPE especially is used as crosslinking and curing agent of the present invention, preferably includes, for example: as the polyfunctional group vinyl compound of Vinylstyrene, divinyl naphthalene, divinyl biphenyl etc.; The vinyl benzene methyl ether compound that phenol and the reaction of Ethenylbenzene methyl chloride make; The allyl ether compound that styrene monomer, phenol and chlorallylene reaction make; With trialkenyl isocyanuric acid ester (trialkenylisocyanurate).Particularly, preferably have the trialkenyl isocyanuric acid ester of excellent compatibility, wherein, more preferably triallyl isocyanurate (to call TAIC in the following text) and triallyl cyanurate (to call TAC in the following text).This is because these two crosslinking and curing agents make veneer sheet have low-k and good thermotolerance and reliability.
Perhaps, using (methyl) acrylic compound (methacrylic ester or acrylic compound) also is preferred as crosslinking and curing agent of the present invention.Especially, more preferably use three to five functional (methyl) acrylic compound with respect to 3~20 quality % of PPE resin combination total amount.As this three to five functional methacrylate compound, can use trihydroxy methyl propane trimethyl acrylate (TMPT) etc., and three to five functional acrylic compound can use trimethyol propane triacrylate etc.The thermotolerance of the veneer sheet that the further raising of the adding of these crosslinking and curing agents finally obtains.
Also can use though functional group's number is lower than or surpass (methyl) acrylic compound of 3 to 5, use three to five functional (methyl) acrylic compound can farthest improve the thermotolerance of gained veneer sheet.Promptly use three to five functional (methyl) acrylic compound, if its consumption is less than 3 quality % of PPE resin combination total amount, then might be difficult to give the veneer sheet that finally obtains with enough thermotolerances, might reduce the dielectric characteristics and the wet fastness of final veneer sheet if its consumption surpasses 20 quality %.
The blending ratio of PPE and crosslinking and curing agent is preferably 30/70 to 90/10 (mass parts).When PPE then may cause veneer sheet more frangible during less than 30 mass parts, when surpassing 90 mass parts, PPE then may reduce its thermotolerance.Promptly, for fear of the filling perforation performance decrease (difficulty) that causes resin to IVH because of consistency, this consistency depends on the molecular weight of PPE or depends on PPE and the blending ratio of crosslinking and curing agent solidifying agent such as triallyl isocyanurate that the blending ratio of PPE and crosslinking and curing agent solidifying agent can be determined by above-mentioned in the present invention.In addition, be set in the specific scope, can improve the flowability and the consistency of PPE resin combination, can improve the dielectric characteristics of PPE resin simultaneously by blending ratio with PPE and crosslinking and curing agent.The blending ratio of PPE and crosslinking and curing agent is preferably 50/50 to 90/10, more preferably 60/40 to 90/10 (mass parts).
If needed, PPE resin combination of the present invention can further comprise inorganic or organic filler.Mineral filler can be used to suppress the thermal expansivity of the veneer sheet that made by PPE resin combination of the present invention and improve its rigidity.The mineral filler of using is not particularly limited, can list metal oxide, nitrite, silicide, boride etc., for example silicon-dioxide, boron nitride, wollastonite, talcum, kaolin, clay, mica, alumina, zirconium white, titanium dioxide, or the like.PPE resin combination of the present invention can effectively reduce specific inductivity, therefore preferably uses filler such as the silicon-dioxide and the boron nitride of low-k as mineral filler.
On the other hand, organic filler is mainly used to reduce the specific inductivity of the veneer sheet that is made by PPE resin combination of the present invention.Particularly, can list fluorine class, polystyrene type, Vinylstyrene class, polyimide filler etc., these fillers can be used singly or in combination.Fluorine class filler (filler that is made by fluorochemicals) comprises, for example: polytetrafluoroethylene (PTFE), poly-perfluoroalkoxy resin, poly-ethylene fluoride-acrylic resin, tetrafluoroethylene-polyethylene and ethylene copolymers, poly(vinylidene fluoride), daiflon etc.These mineral fillers and organic filler can be used singly or in combination separately.
Above-mentioned filler should be ground into the particle of reduced size, and purpose is to improve its insulation characterisitic and reliability to satisfy in recent years the trend that requires to lighter, thinner, shorter and littler product and high-density assembling.More particularly, the mean diameter of filler particles is preferably and is no more than 10 μ m.Use such filler can produce the veneer sheet of excellent uniformity coefficient and reliability.Should " mean diameter " can determine, but can decide according to the description of this filler.At present the mean diameter of obtainable most of filler particles be 0.05 μ m or more than, so in fact the lower limit of filler mean diameter is exactly this value.
The mineral filler and the organic filler that are used for PPE resin combination of the present invention can be hollow or porous particles, or by the particle that fluorochemicals is made, its objective is the specific inductivity of further reduction product.This is because use these fillers can produce the veneer sheet with excellent specific inductivity.
With regard to the inorganic hollow particle, its sintering temperature is important, is preferably 600 ℃ or higher.When hollow bead is during with preparation such as sol-gel method, the dielectric characteristics of this hollow bead can worsen, and particularly dielectric loss factor can increase because of silanol residual on it, and may cause the rapid deterioration of broadband character.
With regard to organic filler, can use the open communique 2002-80503 number disclosed hollow polymer micropowder of Japanese Patent.The shell of hollow bead is made by advanced low-k materials such as Vinylstyrene or divinyl biphenyl, and it helps producing the veneer sheet with low-k.
If needed, PPE resin combination of the present invention can further comprise fire retardant, and purpose is to improve water resisting property, moistureproofness, hygroscopic thermotolerance and the glass transition point of veneer sheet.In this case, by the PPE resin combination that contains PPE, crosslinking and curing agent and fire retardant; And in the varnish formed of solvent (organic solvent), it is inert, insoluble but be scattered in bromine compounds in the varnish solvent for use that above-mentioned fire retardant is preferably PPE and crosslinking and curing agent.Promptly, when fire retardant is when having the reactive flame retardant of unsaturated link(age) or being dissolved in the fire retardant of above-mentioned solvent, then this fire retardant is admixed in the reaction system of producing matrix resin, thereby has reduced prepreg that uses these resin combinations and water resisting property, moistureproofness, hygroscopic thermotolerance and the glass transition point (to call Tg in the following text) that uses the veneer sheet of this prepreg.Therefore, when fire retardant does not react on PPE and crosslinking and curing agent and insoluble but when being scattered in bromination organic compound in the solvent, then this fire retardant seems as filler retention in resin, in order to water resisting property, moistureproofness, hygroscopic thermotolerance and the Tg that improves product.In addition, the true specific gravity of bromination organic compound is preferably in 2.0 to 3.5 scope.When the true specific gravity of flame retardant brominated organic compound less than 2.0 the time, then make this fire retardant be difficult to disperse, and when this proportion surpassed 3.5, then this fire retardant trended towards being deposited in the varnish of PPE resin combination, need constantly stir to keep the homogeneous of varnish, cause reducing operation efficiency.
As this bromination organic compound, the optimization aromatic bromine compounds, what it was fit to comprises, for example: ten bromo diphenylethanes, 4,4-'-dibromobiphenyl, ethene two (tetrabromo phthalimide) (ethylene bistetrabromophthalimide), or the like.The content of bromination organic compound is preferably, and with respect to the total amount of resin combination, bromine content drops in the scope of 8 to 20 quality %.When bromine content with respect to the total amount of resin combination during less than 8 quality %, then the resistivity against fire of veneer sheet descends and is difficult to keep the level of fire resistance of UL standard 94V-0, and when this content surpassed 20 quality %, then the thermotolerance of veneer sheet descended and is heated Shi Huigeng and discharges bromine (Br) easily.
In addition, PPE resin combination of the present invention can further comprise initiator, and purpose is to strengthen the effect of crosslinking and curing agent.Though only use PPE (0) and crosslinking and curing agent also can promote curing under the high temperature, add initiator and be advisable, because be difficult to maintenance high temperature curing is finished before sometimes according to processing condition.Should " reaction initiator " be not particularly limited, as long as it can reach the curing that promotes the PPE resin combination in suitable period under suitable temperature, and improve the character of PPE resin such as thermotolerance etc., for example comprise oxygenant, if any α, α '-two (sec.-propyl between tert-butyl hydroperoxide) benzene, 2,5-dimethyl-2,5-two (tert-butyl hydroperoxide)-3-hexin, benzoyl peroxide, 3,3 ', 5,5 '-tetramethyl--1,4-hexichol oxygen quinone, chloranil, 2,4,6-three (tertiary butyl phenoxy group), single carbonic acid tert-butyl hydroperoxide isopropyl ester and Diisopropyl azodicarboxylate.If desired, can further add metal carboxylate with further promotion curing reaction.In the middle of them, as the preferred especially α of initiator, α '-two (sec.-propyl between tert-butyl hydroperoxide) benzene.This is because this compound has: higher reacting initial temperature, therefore when not needing to solidify, as when prepreg is dry, can not cause curing, and can not weaken the stability in storage of PPE resin combination; Low volatility, the dry and anti-devaporation of memory period at prepreg; And excellent stability.
