Patent ID: 10208202

Abstract:
A thermoplastic resin composition includes 10 to 95 parts by weight of a polycarbonate resin (A); 5 to 90 parts by weight of a graft copolymer (B); and 0 to 50 parts by weight of a copolymer (C). The graft copolymer (B) is produced by the graft polymerization of 10 to 80 parts by weight of a rubbery polymer with 20 to 90 parts by weight of a monomer component including an aromatic vinyl monomer and/or a cyanide vinyl monomer, wherein the rubbery polymer has a weight average particle size of 150 to 450 nm and also has a 10 wt % particle size of 50 to 250 nm and a 90 wt % particle size of 450 to 650 nm in a particle size cumulative weight fraction. The copolymer (C) is produced by copolymerizing an aromatic vinyl monomer, a cyanide vinyl monomer and another vinyl monomer with one another.
