Abstract
The present invention relates to a flame retardant polycarbonate thermoplastic resin composition that comprises a polycarbonate resin, a rubber modified vinyl-grafted copolymer, a phosphorous mixture of a cyclic phosphazene oligomer compound and a phosphate ester morpholide compound as a flame retardant, and a fluorinated polyolefin resin, which has good flame retardancy, heat resistance, mechanical strength, impact strength, heat stability, processability, and appearance.
