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 vinyl-grafted copolymer prepared by graft-polymerizing (b (C) about 0 to 50 parts by weight of a vinyl copolymer polymerized with (c (D) about 1 to 30 parts by weight of a phosphorous mixture, as a flame retardant, per 100 parts by weight of (A)+(B)+(C), of (d where R 1 is alkyl, aryl, alkyl substituted aryl, aralkyl, alkoxy, aryloxy, amino or hydroxyl, k and m are an integer from 1 to 10, R 2 is dioxyarylene group of C 6-30 or a derivative thereof, and n is 0 or an integer representing the number of repeating unit and the average value of n in the phosphazene mixture is 0.3 to 3; and (E) 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
