Abstract
Disclosed herein is a thermoplastic resin composition. The thermoplastic resin composition includes: about 100 parts by weight of a polycarbonate resin; about 1 part by weight to about 30 parts by weight of a core-shell type rubber-modified vinyl graft copolymer; about 5 parts by weight to about 50 parts by weight of an aromatic vinyl copolymer resin; and about 5 parts by weight to about 50 parts by weight of a phosphorus flame retardant, wherein the polycarbonate resin includes a first polycarbonate resin having a weight average molecular weight of about 10,000 g/mol to about 30,000 g/mol and a second polycarbonate resin having a weight average molecular weight of about 35,000 g/mol to about 60,000 g/mol, and the core-shell type rubber-modified vinyl graft copolymer is obtained by grafting an alkyl (meth)acrylate monomer to a rubber polymer. The thermoplastic resin composition can have good properties in terms of chemical resistance, impact resistance, flame retardancy, heat resistance, and/or fluidity.
