Abstract:
1. A flame retardant polycarbonate thermoplastic resin composition comprising: about 45 to about 95 parts by weight of a polycarbonate resin; about 1 to about 50 parts by weight of a rubber modified vinyl graft copolymer; about 1 to about 50 parts by weight of a nonlinear vinyl copolymer group, wherein the nonlinear vinyl copolymer group comprises a group of branched vinyl polymers or copolymers prepared by polymerizing a monomer mixture comprising styrene, α-methylstyrene, halogen- or alkyl-substituted styrene, C about 1 to about 30 parts by weight of a phosphorous compound, with reference to 100 parts by weight of the combined weight of the polycarbonate resin, the rubber modified vinyl graft copolymer and the nonlinear vinyl copolymer group; and about 0.05 to about 5 parts by weight of a fluorinated polyolefin resin, with reference to 100 parts by weight of the combined weight of the polycarbonate resin, the rubber modified vinyl graft copolymer and the nonlinear vinyl copolymer group.
