A thermoplastic resin composition comrpising: (A) from 5 to 50 parts by weight of a graft copolymer obtained by graft polymerizing from 20 to less than 40 parts by weight of monomers comprising from 20 to 80% by weight of an alpha -alkyl aromatic vinyl monomer, from 3 to 40% by weight of an aromatic vinyl monomer containing no alpha -alkyl aromatic vinyl monomer, from 15 to 40% by weight of a vinyl cyanide monomer and from 0 to 35% by weight of a vinyl monomer copolymerizable with these monomers, to from more than 60 to 80 parts by weight of a diene rubber-like polymer, the total amount of the monomers and the rubber-like polymer being 100 parts by weight; (B) from 0 to 60 parts by weight of a copolymer obtained by polymerizing from 60 to 90% by weight of an aromatic vinyl monomer, from 10 to 40% by weight of a vinyl cyanide monomer and from 0 to 30% by weight of a vinyl monomer copolymerizable with these monomers; and (C) from 15 to 80 parts by weight of a polycarbonate resin; the total amount of components (A), (B) and (C) being 100 parts by weight. The composition is useful for making molded products. |
