Description

POLYCARBONATE MOLDING MASSES FOR MANUFACTURE OF ARTICLES WITH DUST FIXATION DECREASED. Field of the invention. The object of the invention are transparent, pohcar-bonate molding compositions, for articles of synthetic material, which contain at least one thermostabilizer and an auxiliary agent for demolding and which have a lower tendency to fix the powder. Description of the prior art. The fixation of dust in the molded bodies of synthetic material is a very widespread problem. For example, the publication by Saechtling, Kunststoff-Taschenbuch, 26th edition, Hanser Verlag, 1995, München, page 140 et seq. By way of example, dust is deposited, during storage, under industrial conditions on the injection molded bodies. The dust deposits are particularly damaging and limit their function in the case of transparent shaped bodies. An important industrial thermoplastic is polycarbonate. This is used in transparent approaches for example for the optical data storage sector, in automotive engineering, in the construction sector, for liquid containers or for other optical applications. A dust setting is undesirable for all these applications of polycarbonate and can negatively influence the function. A known method for preventing the fixation of dust on the molded bodies of synthetic material consists of the use of antistatics. Antistatics for thermoplastics have been described in the literature (see for example G chter, Müller, Plastic Additives, Hanser Verlag, München, 1996, pages 749 and REF. 134081 following), which limit the dust bindings. These antistatics improve the electrical conductivity of the plastic molding materials and derive the surface loads, which are generated during manufacture and use. In this way, the dust particles are no longer attracted and, as a result, less dust bindings are produced. In this case, a distinction is made between internal and external antistats. An external antistatic is applied superficially after processing on the molded bodies of synthetic material, an internal antistatic is added as an additive during processing. For economic reasons it is desirable, in most cases, the use of internal antistats, since no additional work stage is required for the surface application of the antistatic after processing. However, no internal antistatic is known for the transparent polycarbonate approaches, which effectively limits the dust fixations and which, at the same time, does not adversely affect the advantageous properties of this material such as high transparency, low turbidity and high resilience A drawback of the addition of antistatics can be considered in that they increase the production costs of an object as with any additive added. It would therefore be desirable in general that the smallest possible proportion of additives (in number and quantity) be sufficient. In addition, the images of the dust figures have great significance for aesthetic reasons. In the usual molding compositions, harmful structures are often produced in the form of bushes or round structures with dimensions of 1 to 20 mm. Such powder figures with fine branches are visible to the naked eye with great intensity because they show great contrasts between dust-covered spots and dust-free nearby spots. Molding masses would be desirable which would form, on the surface, powder figures of large surface area or cover them in the most homogeneous manner possible. Detailed description of the invention. Surprisingly, suitable combinations of additives have been found, by means of which it can be strongly limited, as a whole, the fixation of dust and with which the powder figures of fine ramifications can be broadly prevented. In this case the addition of antistatics can be abandoned. The task was solved according to the invention by means of a thermoplastic molding compound, containing polycarbonate as a thermoplastic, amorphous polymer, and at least one antioxidant and an auxiliary agent for demolding, the antioxidant containing at least one stabilizer of the group.

The preparation of these polycarbonates is carried out in a known manner from diphenols, carbonic acid derivatives, optionally chain terminators and, optionally, branching agents. Details on obtaining polycarbonates have been described in many patent publications for approximately 40 years. By way of example reference will be made here only to Schnell's publications, "Chemistry and Physics of Polycarbonates", Polymer Reviews, Volume 9, Interscience Publishers, New York, London, Sydney 1964, by D. Freitag, U. Grigo, P.R. Müller, H. Nouvertne ', BAYER AG, "Polycarbonates" in Encyclopedia of Polymer Science and Engineering, Volume 11, Second Edition, 1988, pages 648-718 and, finally, by Drs.

These and other suitable diphenols are described, for example, in US Pat. Nos. 3 028 635, 2 999 835, 3 148 172, 2 991 273.3 271 367, 4 982 014 and 2 999 846, in the published German patent applications, not examined 1 570 703, 2 063 050, 2 036 052, 2 211 956 and 3 832 396, in the specification of the French patent 1 561 518, in the monograph "H. Schnell, Chemistry and Physics of Polycarbonates, Interscience Publishers , New York 1964"as well as in published Japanese patent applications, not examined 62039/1986, 62040/1986 and 105550/1986. In the case of the homopolycarbonates, only one diphenol has been used; in the case of the copolycarbonates, several diphenols have been used. Suitable carbonic acid derivatives are, for example, phosgene or diphenyl carbonate. Suitable chain breakers are both monophenols and also monocarboxylic acids. Suitable monophenols are phenol itself, alkylphenols such as cresol, p-tert-butylphenol, pn-octylphene-nol, p-iso-octylphenol, pn-nonylphenol and p-iso-nonylphenol, halogenphenols such as p-chlorophenol, , 4-dichlorophenol, p-bromophenol and 2,4,6-tribromophenol, 2,4,6-triiodo-phenol, p-iodophenol, as well as their mixtures. The preferred chain breaker is p-tert-butylphenol. Suitable monocarboxylic acids are benzoic acid, alkylbenzoic acids and halogenobenzoic acids. The preferred chain terminators are the phenols of the formula (I) where R means hydrogen, tere. -butyl or a branched or unbranched alkyl moiety with 8 and / or 9 carbon atoms.

The amounts of the chain switches, to be used, amount to 0.1 mol% to 5 mol%, based on the moles of the diphenols used in each case. The addition of the chain switches can be carried out before, during and after phosgenation. Suitable branching agents are trifunctional compounds, or with a functionality greater than three, known in the chemistry of polycarbonates, especially those with three or more than three phenolic OH groups. Suitable branching agents are, for example, phloroglucin, 4,6-dimethyl-2,4,6-tri-3,4-hydroxyphenyl) -heptene-2,4,6-dimethyl-2,4,6-tri- ( 4-hydroxyphenyl) -heptane, 1, 3,5-tri- (4-hydroxyphenyl) -benzene, 1, 1-tri- (4-hydroxyphenyl) ethane, tri- (4-hydroxy-phenyl) -phenyl-methane, 2,2-bis- [4,4-bis- (4-hydroxyphenyl) -cyclohexyl] -propane, 2,4-bis- (4-hydroxyphenyl-isopropyl) -phenol, 2,6-bis- (2-hydroxy) -5'-methyl-benzyl) -4-methylphenol, 2- (4-hydroxyphenyl) -2- (2,4-dihydroxyphenyl) -propane, esters of hexa- (4- (4-hydro-xyphenyl-isopropyl)) phenyl) -ortoterephthalic, tetra- (4-hydroxyphenyl) -methane, tetra- (4- (4-hydroxyphenyl-isopropyl) -phenoxy) -methane and 1,4-bis- (4 ', 4"-dihydroxytriphenyl) -methyl) -ben-ceno, as well as 2,4-dihydroxybenzoic acid, trimesinic acid, cyanuryl chloride and 3,3-bis- (3-methyl-4-hydroxyphenyl) -2-oxo-2, 3-dihydroindole The amount of branching agents used, if appropriate, ranges from 0.05 mol% to 2 mol%, in turn referred to the moles of the diphenols, read in each case. The branching agents can be prepared either with the diphenols and with chain terminators in the alkaline, aqueous phase, or they can be added before phosgenation dissolved in an organic solvent. In the case of the transesterification procedure, the branching agents are used together with the diphenols. All these measures for obtaining the thermoplastic polycarbonates are known to the person skilled in the art. It is possible, in order to achieve improved positions, that at least one other additive, usually present in the thermoplastic synthetic materials, preferably in the poly- and copolycarbonates, such as for example flame retardants, fillers, foaming agents, is also contained. dyes, pigments, optical brighteners, catalysts for transesterification and nucleating agents or the like, preferably in amounts, respectively, of up to 5% by weight, preferably from 0.01 to 5% by weight, based on the whole of the mixture, particularly preferably from 0.01% by weight to 1% by weight, based on the amount of the synthetic material. The polymer compositions obtained in this way can be transformed into molded objects according to the usual methods such as for example hot-pressing, spinning, extrusion or injection-casting, such as for example toy parts as well as fibers, sheets, tapes, plates, ribbed plates, containers, pipes and other types of profiles. The polymer compositions can also be transformed to cast sheets. The invention therefore also relates to the use of the polymer compositions according to the invention for the production of a molded object. It is also interesting to use systems with several layers. In this case, the polymer composition according to the invention will be applied, in a thin layer, on a molded object constituted by a traditional polymer. The application can be carried out simultaneously or immediately after the molding of the base object, for example by coextrusion or injection molding of several components. However, the application can also be carried out on the molded, finished base bodies, for example by lamination with a film or by coating with a solution.

The polycarbonate molding compositions according to the invention can be formed into molded bodies, for example, the polycarbonates being isolated, in a known manner, to form a granulate and this granulate can be processed, if necessary after addition of the aforementioned additives, by casting by injection to give diverse articles, in a known way. The shaped bodies constituted by the polycarbonate molding compositions according to the invention can be used within a broad spectrum, especially when the fixing of powder for the aforementioned reasons is undesirable. The application is particularly suitable in the case of optical data carriers, such as for example CDs, automotive components, such as for example glazing elements, plastic diffuser discs, in addition to the use in extracted plates, such as for example, solid plates, double rib plates or multiple rib plates, optionally also with one or several coextracted layers, as well as the application in injection-molded parts, such as containers for edible articles, components of electrical appliances, in glasses for spectacles or Ornamental objects The polycarbonate molding compositions according to the invention can also be mixed with other customary polymers. In this case, transparent synthetic materials are particularly suitable. Transparent thermoplastics, more preferably polymers of ethylenically unsaturated monomers and / or polycondensates of bifunctional, reactive compounds, will preferably be used as clear synthetic materials. Especially suitable synthetic materials for these mixtures are poly- or copolyacrylates and poly- or copolymethacrylates such as, for example, poly- or copolymethacrylates of methyl, as well as especially copolymers with styrene such as for example transparent polystyrene-acrylonitrile (SAN), in addition cycloolefins transparent, poly- or copolycondensed terephthalic acid, such as for example poly- or copolyethylene terephthalate (PET or CoPET) or PET (PETG) modified with glycol. Examples In order to obtain molding compositions or test specimens, a non-stabilized additive-free polycarbonate (Makrolon® 2808 from Bayer AG, Leverkusen) with a molecular weight will be mixed, if not indicated otherwise. average of approximately 30,000 (Mw according to the GPC), viscosity in solution:? = 1, 293 at 340 ° C in a two-shaft extruder with the indicated amount of additive and then granulated. Rectangular plates (155 mm x 75 mm x 2 mm) are then injected from this granulate. In order to be able to test the dust fixation in a laboratory test, the injected plates are subjected to an atmosphere with dust in suspension. A 2 liter beaker is filled with a magnetic stirring rod, with a length of 80 mm, of triangular cross-section, with the corresponding powder up to a height of approximately 1 cm. With the help of a magnetic stirrer the powder is suspended. After stopping the agitator, the test piece is subjected to this dust atmosphere for 7 seconds. According to the specimen used, a greater or lesser amount of powder is fixed on the specimens. The transmission and turbidity according to the ASTM standard 1003 are then determined with the Haze-Gard plus device from the firm BYK-Gardner GmbH, D-82538 Geretsried. In the case of irregular dust fixations, the average value of several measurements is determined. Transmission and turbidity are measured at 18 points, which are distributed in a grid pattern 6x3 homogeneously on the rectangular plate. As a powder, coal dust (in this case 20 g of activated carbon, Riedel-de Haen, Seelze, Germany, article No. 18003) is used. In addition, the weight increase of the plate after dusting is measured. A traditional Mettler Toledo AE200 laboratory scale is used (table 3). The evaluation of the powder figures in table 2 is carried out with the naked eye. The plates that present powder figures with fine ramifications or that show high contrasts are evaluated negatively (-), those with homogeneous and large surface powder figures are evaluated with (+).

Tables 1 to 3 clearly show that the molded bodies constituted by the molding compositions according to the invention attract a smaller amount of dust, have an improved transmission after dusting and form optically prettier powder figures with a larger surface area, than those that come from the traditional molding masses. It is noted that, with regard to this date, the best method known to the applicant, to carry out the aforementioned invention, is that which is clear from the present description of the invention.
