(57) [Summary] [Object] To provide a novel curable polyphenylene ether resin composition having excellent dielectric properties of polyphenylene ether and exhibiting excellent chemical resistance and heat resistance after curing. (A) Reaction product of polyphenylene ether with unsaturated carboxylic acid or unsaturated carboxylic acid anhydride, and (b) diallyl phthalate, divinylbenzene, polyfunctional acryloyl compound, polyfunctional methacryloyl compound, poly At least one selected from the group consisting of a functional maleimide, a polyfunctional cyanate ester, a polyfunctional isocyanate, an unsaturated polyester, an epoxy resin, a phenol resin, and a polybutadiene polymer. A base material is impregnated with a curable resin composition comprising one compound and / or its prepolymer, and (c) a thermoplastic resin to obtain a composite material. The composite materials are laminated, heated and cured. |
