摘要： This invention relates to a resin composition having high impact strength at low temperatures, comprising a polyamide, a graft copolymer obtained by graft polymerizing a monomer mixture of an aromatic vinyl monomer and a vinyl cyanide monomer to a conjugated diene rubber, a copolymer comprising an aromatic vinyl monomer, a vinyl cyanide monomer and other vinyl monomer copolymerizable with the aromatic vinyl monomer and the vinyl cyanide monomer, a modified hydrogenated block copolymer comprising a conjugated diene rubber and styrene or its derivatives to which has been grafted an unsaturated carboxylic acid or an unsaturated carboxylic anhydride, a copolymer comprising an aromatic vinyl monomer, a maleimide monomer, an unsaturated carboxylic acid or an unsaturated carboxylic anhydride, and other vinyl monomer copolymerizable with the aromatic vinyl monomer, and a graft copolymer obtained by graft polymerizing a maleic anhydride to an ethylene-propylene rubber.
