Abstract:
1. A flame retardant thermoplastic resin composition comprising: (A) about 45 to 95 parts by weight of a polycarbonate resin; (B) about 1 to 50 parts by weight of a rubber modified styrene-grafted copolymer prepared by graft-polymerizing (C) about 0.5 to 50 parts by weight of a styrene-containing copolymer polymerized with (D) about 0.5 to 50 parts by weight of a (meth)acrylic acid ester copolymer polymerized with (E) about 1 to 30 parts by weight of a phosphate ester morpholide composition as a flame retardant; and (F) about 0.05 to 5.0 parts by weight of a fluorinated polyolefin resin with average particle size of  about 0.05 to 1000 μm and density of about 1.2 to 2.3 g/cm wherein the phosphate ester morpholide composition is represented by the following formula (III): where R 7 , is a C 6-20 aryl group or an alkyl-substituted C 6-20 aryl group, R 8 is a C 6-30 aryl group or an alkyl-substituted C 6-30 aryl group, y is 1 or 2, and m is the average number of morpholide repeating units, n is the average number of R 7 repeating units, and m+n is 0 to 3.
