Abstract
A polycarbonate resin composition of the present invention comprises (A) about 30 to about 95 parts by weight of thermoplastic polycarbonate resin; (B) about 1 to about 50 parts by weight of rubber-modified-vinyl graft copolymer; (C) about 0 to about 50 parts by weight of vinyl copolymer; and (D) about 1 to about 50 parts by weight of amorphous thermoplastic polyester copolymer. The resin composition of the present invention can have excellent physical properties such as weld line strength, fluidity, impact resistance, and heat resistance.
