Abstract
The present invention relates to flameproof thermoplastic resin compositions comprising (A) a base resin consisting of (1) 80 to 96% by weight of a thermoplastic, halogen-free polycarbonate, and (2) 4 to 20% by weight of a core-shell type ABS resin with a graft index of 40 or above, which is obtained by grafting 25 to 45% by weight of a styrene and 10 to 15% by weight of an acrylonitrile onto 45 to 60% by weight of a butadiene rubber, (B) 5 to 20 parts by weight, per 100 parts by weight of the base resin(A), of a phosphate composition, and (C) 0.1 to 2.0 parts by weight, per 100 parts by weight of the base resin(A), of a perfluoroalkane polymer. The phosphate composition is represented as the general formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 independently of one another are C.sub.6 -C.sub.20 aryl or alkyl-substituted C.sub.6 -C.sub.20 aryl, n is 0 to 5, and the average n of the phosphate composition is, n is 0 to 5, about 0.3 to 0.8.
