Abstract
A polycarbonate resin composition comprises: about 30 to about 99% by weight of a polycarbonate resin (A); and about 1 to about 70% by weight of a rubber modified aromatic vinyl based copolymer resin (B); and about 0.1 to about 40 parts by weight of a phosphorous compound (C) including a phosphate compound (C1) and a phosphonate compound (C2), per 100 parts by weight of a base resin including (A) and (B). The polycarbonate resin composition can have excellent flame retardancy and improved heat resistance by using a combination of at least two different phosphorous compounds.
