Abstract: A thermoplastic resin composition comprising: (A) a polyamide having a relative viscosity in sulfuric acid of not less than 2.0 and less than 3.0, (B) a graft copolymer obtainable by copolymerizing an aromatic vinyl monomer, a cyanated vinyl monomer and another vinyl monomer copoly- merizable with the two former monomers in the presence of a rubbery polymer and (C) a carboxylic acid-modified copolymer comprising monomeric units derived from an aromatic vinyl monomer, a cyanated vinyl monomer and an .alpha. ,.beta. -unsaturated monocarboxylic acid wherein the weight ratio of polyamide (A) to a total amount of the graft copolymer (B) and the carboxylic acid-modified copolymer (C) is from 90:10 to 10:90, the content of .alpha., .beta.-unsaturated monocarboxylic acid is 0.1 to 1.5% by weight based on the total amount of the graft copolymer (B) and the carboxylic acid-modified copolymer (C), and the content of rubbery polymer is 5 to 30% by weight based on the whole weight of the composition. The thermo- plastic resin composition is useful as a material for machine parts, electrical parts and automobile parts.
