Abstract
An impact resistant thermoplastic resin composition which comprises: 100 parts by weight of a resin mixture comprising from 20 to 80% by weight of a polyamide resin (A) and from 20 to 80% by weight of a graft copolymer (B) composed of from 45 to 60 parts by weight of a conjugated diene rubber and from 40 to 55 parts by weight of a monomer mixture comprising from 60 to 80% by weight of an aromatic vinyl monomer component and from 20 to 40% by weight of a vinyl cyanide monomer component (provided that the total amount of said monomer mixture is 100% by weight) wherein the average particle size of graft rubber is from 0.2 to 1.0 .mu.m, the graft ratio is from 40 to 80%, and the weight average molecular weight of a resinous component composed of said monomer components is from 220,000 to 450,000; from 0.01 to 40 parts by weight of a copolymer (C) comprising from 50 to 80% by weight of an aromatic vinyl monomer component, from 0.01 to 30% by weight of an .alpha., .beta.-unsaturated dicarboxylic anhydride monomer component, from 5 to 47% by weight of at least one monomer component selected from the group consisting of an N-substituted maleimide monomer component and a vinyl cyanide monomer component, and from 0 to 30% by weight of a methyl methacrylate monomer component (provided that the total amount of the monomer components is 100% by weight); and
