Abstract:
A flame-retardant thermoplastic resin composition consisting essentially of the following components (A) to (D):(A) 50 to 80 parts by weight of an aromatic polycarbonate resin;(B) 5 to 40 parts by weight of a rubber-reinforced thermoplastic resin prepared by graft-polymerizing monomer components comprising an aromatic vinyl monomer, a vinylcyanide monomer and optionally other copolymerizable vinyl-based monomers, with a rubber polymer, the amount of said vinylcyanide monomer used being not less than 0.5% by weight and less than 5% by weight based on the total weight of said monomer components;(C) 5 to 30 parts by weight of phosphate represented by the formula (I): ##STR4## wherein R.sup.1 to R.sup.3 are the same or different and are independently an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms; and n is 0 or 1,the total amount of the (A), (B) and (C) components being 100 parts by weight; and(D) 0.02 to 3 parts by weight of polytetrafluoroethylene based on the total weight of the (A), (B) and (C) components.
