Abstract

Disclosed herein is a flame retardant polycarbonate resin composition having high heat resistance and good impact resistance. The flame retardant polycarbonate composition is prepared by incorporating into a polycarbonate resin a silicon-based core-shell graft copolymer, in which a vinyl monomer is graft polymerized onto a rubber comprising about 20 to about 95% by weight of silicon, and optionally a phosphoric acid ester compound. The present invention can accordingly provide superior flame retardance while maintaining good impact resistance, high flowability and high heat resistance.
