Conventionally, upstream polyimide resins and epoxy resins have been frequently used as resins for laminates and the like. In the case of laminates, polyimide resins and epoxy resins are used depending on whether the number of laminated layers is 10 or more or less, as a criterion for resin selection. However, in recent years, the uses of laminates have diversified, and it is no longer possible to adequately handle the use of polyimide resins and epoxy resins. Polyimide resins are required to have high Tg, high flame retardancy, low temperature curing, low cost, etc., and epoxy resins are required to have high purity, fast curing property, smear property, U It is required to be excellent in V a hostility, etc. In particular, recently there has been a demand for performance that is between polyimide resin and epoxy resin, and blends of both resins and epoxy-modified polyimide resin prepolymers, which are polyimide resin prepolymers modified with epoxy resins, have been developed. , the present inventors have already developed this type of prepolymer, and have published Japanese Patent Application No. 168219/1982, Japanese Patent Application No. 168220/1983,

In conventional blends of polyimide resin and epoxy resin or epoxy-modified polyimide resin prepolymers, the amount of epoxy resin blended is increased to increase interlayer adhesion, but this increases the Tg of the resin after curing. There was a problem with it being too low. The present invention was made in view of the above circumstances, and its purpose is to provide an epoxy-modified polyimide resin preform with a high Tg and excellent heat resistance, and which can provide sufficient interlayer adhesive strength even when made into a laminate. Our goal is to provide polymers.

The epoxy modified polyimide resin prepolymer of the present invention is
A reaction product obtained by reacting an aromatic compound having a plurality of imide groups and a plurality of amino groups in each molecule with a polyimide resin having three or more imide groups in one molecule and an epoxy resin. This configuration achieves the above object. In the present invention, the aromatic compound having a plurality of imide groups and a plurality of amino groups in the molecule (wherein, X represents a terminal functional group, Ar, Ar2 are divalent aromatic groups, and R1 is a hydrogen atom) , an alkyl group having 1 to 10 carbon atoms, R2 represents a hydrogen atom, an alkyl group having 1 to 2' carbon atoms, an alkoxy group, or a hydroxyl group, and 11 represents an integer of 0 to 80). imide (wherein Ar1 is a divalent aromatic group, Ar2 is a tetravalent aromatic group, Ar3 is a trivalent aromatic group, n and m are 0 or a positive integer (however, n++n> 0)), or an amide-imide polymer represented by the general formula (wherein, Ar is a tetravalent aromatic group, R1 and R2 represent a hydrogen atom, a halogen atom, or an alkyl group, and R2 At least one of them is always an alkyl group. +1 is a positive integer.)
Examples include aromatic amines represented by these compounds, and these compounds may be used alone or in combination of two or more. In addition, polyimide resins having three or more imide groups in one molecule are represented by the general formula (wherein, R represents a hydrogen atom, a halogen atom, or an alkyl group, and 11 is a positive integer). Mention may be made of polyfunctional maleimide resins. In addition, the epoxy resin used in the present invention may be one obtained by reacting bis7er7-el A with epichlorohydrin, or one obtained by reacting novolac type phenol, 0-cresol, and epichlorohydrin for use in printed wiring boards. Epoxy resin is used. Examples of brominated epoxy resins include brominated novolak epoxy resins represented by the general formula (in the formula, 11 is a positive integer), diallyl esterified products of tetrabromobisphenol A represented by the formula %, and A diglycidyl ether of tetrabromobisphenol A represented by the following formula is used. The bromine contained in this brominated epoxy resin is preferably 6% by weight or more based on the total resin content. If it is less than 6% by weight, sufficient flame retardancy cannot be ensured. In the present invention, an aromatic compound having a plurality of imide groups and a plurality of amino groups each in the molecule and three imide groups in one molecule are used.
The reaction product obtained by reacting a polyimide resin having more than
Aromatic compounds and polyimide resins are DMF, DMAc, M
It is dissolved in an organic solvent such as C and reacted. The weight ratio of aromatic compound to polyimide resin is 10-20:1. The reaction temperature is 80-120°C and the reaction time is 10-30 minutes. If the temperature is lower than 80°C, the reaction acid may not dissolve, whereas if it exceeds 120°C, the reaction tends to proceed too much, making it difficult to prepare a resin face for prepreg. Next, the obtained reaction product is reacted with an epoxy resin under the same reaction conditions. The ratio of the epoxy resin to the polyimide resin can be up to 2:1 by weight. A resin varnish is prepared from the epoxy-modified polyimide resin prepolymer thus produced, and a base material such as glass cloth, nonwoven fabric, paper, etc. is impregnated with it and dried to produce a prepreg. Multiple sheets of this prepreg are laminated and molded, and metal foil such as copper foil or aluminum foil is adhered to one or both sides of the prepreg to obtain a laminate with excellent heat resistance and interlayer adhesion for printed wiring boards. . In addition, curing agents, fillers such as silica, glass fibers, coupling agents, coloring agents, mold release agents such as calcium stearate, diluents, etc. are added to this epoxy-modified polyimide resin prepolymer to create materials for encapsulating electronic components. is manufactured. The present inventors have developed an aromatic compound having a plurality of imide groups and a plurality of amino groups in each molecule, and an aromatic compound having a plurality of imide groups and three amino groups in one molecule.
It has been found that a laminate with excellent heat resistance and interlayer adhesion can also be obtained from a mixture obtained by blending an epoxy resin with a reaction product obtained by reacting polyimide resins having at least 100% of polyimide resins. Next, embodiments of the present invention will be explained. In the following, parts indicate parts by weight. (Example 1) BiBe5t Lex"5M-20" (
Polyfunctional maleimide l'-MP-2000XJ (trade name, Mitsubishi Yuka Co., Ltd.) 42 as a polyimide resin having three or more imide groups in one molecule and 375 parts (trade name, manufactured by Sumitomo Chemical Co., Ltd.) part was dissolved in DMF and allowed to react at 80°C for 10 minutes. Next, bis7er7-el A type epoxy resin "R-140QJ (trade name, Mitsui Petrochemical Co., Ltd.) was added to the resulting reaction solution.
) and 291 parts of brominated bis7-el/A type epoxy resin rBRENJ (trade name, Nippon Kayaku) were added and reacted at 80° C. for 10 minutes. In this way, an epoxy-modified polyimide resin prepolymer was produced. The glass transition temperature (Tg ('C
)) and thermal decomposition onset temperature (T, G, A('C)) were measured. The results are shown in Table 1. In addition, a varnish was prepared from an epoxy-modified polyimide resin prepolymer, impregnated into a glass cloth base material and dried to create a prepreg, and a plurality of sheets of this prepreg were laminated and molded to obtain a copper-clad laminate with a thickness of 0.4 mm. . The interlayer adhesive strength and copper foil peel strength of this laminate were measured. The results are shown in Table 1. (Example 2) An epoxy-modified polyimide resin prepolymer was produced in the same manner as in Example 1 except that polyfunctional maleimide [MP-2000XJ2i] was used, a copper-clad laminate was prepared, and the same measurements were performed. The results are shown in Table 1. (Comparative Example 1) 410 parts of r″Be5t Lex″SM 20 J, 280 parts of [R-140QJ and 1 part of rBRENJ29' were dissolved in DMF and reacted at 80°C for 10 minutes to produce an epoxy-modified polyimide resin prepolymer. A copper-clad laminate was prepared in the same manner as in Example 1, and the same measurements were performed. The results are shown in Table 1. (Comparative Example 2) A laminate was manufactured in the same manner as in the example except that a polyimide resin varnish having a Tg of 250° C. was used, and the same measurements were performed. The results are shown in Table 1. (Comparative Example 3) A laminate was manufactured in the same manner as in the example except that an epoxy resin varnish having a Tg of 150° C. was used, and the same measurements were performed. The results are shown in Table 1. Example Comparative example Tg ('C) 240 235 228 250

In the present invention, an aromatic compound having a plurality of imide groups and a plurality of amino groups each in the molecule and three imide groups in one molecule are used.
Since the epoxy resin is reacted with the reaction product obtained by reacting the polyimide resin having 1 or more polyimide resins, the rigidity of the skeleton increases due to the reaction between the aromatic compound and the polyimide resin, and as a result, the Tg increases. It has excellent heat resistance, and the epoxy resin component ensures sufficient interlayer adhesion even when it is made into a laminate, making it applicable to a variety of uses.
