The invention provides polyamide/rubber-reinforced styrene resin compositions (particularly a polyamide/ABS resin composition) which are well balanced between impact resistance and flowability and are excellent in heat resistance, chemical resistance, and coatability; and moldings thereof. The compositions are characterized by comprising 100 parts by weight of a thermoplastic resin consisting of (A) 79.5 to 20 parts by weight of a polyamide resin, (B) 20 to 79.5 parts by weight of a polymer obtained by grafting a specific rubbery polymer with an aromatic vinyl monomer and a vinyl cyanide monomer, (C) 0.5 to 60 parts by weight of an unsaturated carboxylic acid-modified copolymer obtained by copolymerizing an unsaturated carboxylic acid with an aromatic vinyl monomer and a vinyl cyanide monomer, and (D) 0 to 50 parts by weight of a copolymer obtained by copolymerizing an aromatic vinyl monomer with a vinyl cyanide monomer (with the proviso that the total amount of the components (A), (B), (C), and (D) is 100 parts by weight) and, if necessary, (E) 0.05 to 150 parts by weight of an inorganic filler. |
