Unsaturated copolymer resin composite

Claim 1

An unsaturated copolymer resin composite prepared by subjecting 100 parts by weight of an unsaturated copolymer resin to conditions of radical graft polymerization together with more than 0 parts by weight but up to 300 parts by weight of a monomer capable of radical polymerization, said unsaturated copolymer resin being a copolymer composed of at least α-olefin selected from the group consisting of ethylene, propylene, 1-butene, 3-methyl-I-butene and 4-methyl-1-pentene, and at least one aliphatic nonconjugated diene represented by the following general formula (I), the content of said aliphatic nonconjugated diene being 0.05 to 50 mol %, and said unsatured copolymer resin having an elastic modules of 500 to 80,000 kg/cm 2 ; ##STR3## wherein n is an integer of 1 to 10; and R 1 , R 2 and R 3 are each a hydrogen atom or an alkyl group having 1-8 carbon atoms, wherein said monomer capable of radical polymerization is at least one member selected from the group consisting of styrene, α-methylstyrene, vinyl chloride, acrylonitrile, vinyl acetate, esters of acrylic acid, methacrylic acid, maleic acid or fumaric acid wherein the alcohol component contains an alkyl moiety having 1 to 8 carbon atoms, glycidyl acrylate, glycidyl methacrylate, an alkyl (C 1-8 ) glycidyl maleate, an alkyl (C 1-8 ) glycidyl fumarate, and maleic anhydride.
