Conventionally, polyimide resins and epoxy resins have been widely used as resin varnishes for laminated boards. 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,
It is required to have excellent fast curing properties, smear properties, UV shielding properties, 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 resin-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 filed a patent application in 1982-

In the case of conventional blends of polyimide resin and epoxy resin or epoxy-modified polyimide resin prepolymers, in order to increase interlayer adhesion,
Although the amount of epoxy resin blended is large, there is a problem that the Tg of the resin after curing becomes 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 adhesion even when made into a laminate. An object of the present invention is to provide a prepreg impregnated with a polymer.

( R2 represents a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkoxy group, or a hydroxyl group, and n represents an integer of 0 to 80) and a terminally functional imide represented by the general formula (In the formula, R 1 and R 2 represent a hydrogen atom, a halogen atom, or an alkyl group, at least one of R 1 and R 2 is always an alkyl group, and n represents a positive integer) This method is characterized by impregnating a base material with an epoxy-modified polyimide resin prepolymer obtained by reacting a polyfunctional maleimide resin and then reacting with an epoxy resin, and with this configuration, the above object is achieved. It is. The terminal functional imide in the present invention has a plurality of imide groups and a plurality of amino groups in one molecule,
general formula (In the formula, X represents a terminal functional group, Ar 1 and Ar 2 are divalent aromatic groups, R 1 is a hydrogen atom, and has a carbon number of 1 to 10
R2 represents a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkoxy group, or a hydroxyl group, and n represents an integer of 0 to 80. In addition, polyfunctional maleimide resin has three or more imide groups in one molecule and has the general formula (In the formula, R 1 and R 2 represent a hydrogen atom, a halogen atom, or an alkyl group, at least one of R 1 and R 2 is always an alkyl group, and n represents a positive integer) . In addition, the epoxy resin used in the present invention is one obtained by reacting bisphenol A with epichlorohydrin, or an epoxy resin obtained by reacting novolac type phenol, o-cresol, and epichlorohydrin for printed wiring boards. be done. In addition, as a brominated epoxy resin, the general formula (In the formula, n is a positive integer) Brominated novolac epoxy resin,
formula The diallyl ester of tetrabromobisphenol A represented by the formula A diglycidyl ether of tetrabromobisphenol A represented by the following formula is used. The bromine contained in this brominated epoxy resin is preferably in the range of 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, the reaction product obtained by reacting a terminally functional imide resin and a polyfunctional maleimide resin is reacted with an epoxy resin. First, the terminally functional imide resin and the polyfunctional maleimide resin are mixed in DMF, Dissolve in an organic solvent such as DMAc or MC and react. The weight ratio of the terminally functional imide resin to the polyfunctional maleimide is 10 to 20:1. The reaction temperature is 80-120°C and the reaction time is 10-30 minutes. If the temperature is lower than 80℃, the reaction components may not dissolve, while if it exceeds 120℃, the reaction will proceed too much.
Preparation of resin varnish for prepreg tends to be difficult. Next, the obtained reaction product is reacted with an epoxy resin under the same reaction conditions. The ratio of the epoxy resin to the polyfunctional maleimide resin can be up to 2:1 by weight. A resin varnish is prepared from the epoxy-modified polyimide resin prepolymer produced in this way,
A prepreg is produced by impregnating a base material such as glass cloth, nonwoven fabric, or paper and drying it. 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, this epoxy-modified polyimide resin prepolymer is coated with a curing agent, fillers such as silica, glass fiber,
A coupling agent, a coloring agent, a mold release agent such as calcium stearate, a diluent, and the like are added to produce an electronic component sealing material. Next, embodiments of the present invention will be described. In the following, parts indicate parts by weight. (Example 1) Terminal functional imide resin “Best Lex” SM-20 having multiple imide groups and multiple amino groups in one molecule
(Product name, manufactured by Sumitomo Chemical Co., Ltd.) 375 parts and polyfunctional maleimide "MP-2000X" having 3 or more imide groups in one molecule (Product name, manufactured by Mitsubishi Yuka Co., Ltd.) 42
part was dissolved in DMF and reacted at 80°C for 10 minutes. Then, bisphenol A was added to the resulting reaction solution.
Injected 280 parts of type epoxy resin "R-140Q" (trade name, manufactured by Mitsui Petrochemical Co., Ltd.) and 291 parts of brominated bisphenol A type epoxy resin "BREN" (trade name, manufactured by Nippon Kayaku). 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 TGA (°C) of this material were measured. The results are shown in Table 1. Next, 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 0.4 mm thick copper-clad laminate. 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 21 parts of the polyfunctional maleimide "MP-2000X" was used, a copper-clad laminate was made, and the same measurements were performed. . The results are shown in Table 1. (Comparative example 1) 410 copies of “Best Lex” SM-20 and “R-140Q”
Dissolve 280 parts and 291 parts of "BREN" in DMF at 80℃
An epoxy-modified polyimide resin prepolymer was produced by reacting for 10 minutes, and 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.

In the present invention, since a base material is impregnated with an epoxy-modified polyimide resin prepolymer obtained by reacting a specific terminal functional imide with a specific polyfunctional maleimide resin and then reacting with an epoxy resin, the terminal The reaction between the functional imide and the polyfunctional maleimide resin increases the rigidity of the skeleton, resulting in a high Tg and excellent heat resistance.The epoxy resin content also provides sufficient strength when made into a laminate. It ensures interlayer adhesion and can be applied to a variety of applications.
