The present invention relates to flameproof thermoplasticnresin compositions comprising (A) a base resin consisting of (a 1 )n80 to 96 % by weight of a thermoplastic, halogen-freenpolycarbonate, and (a 2 ) 20 to 4 % by weight of a styrene-containingngraft copolymer with a graft index of 40 to 90 % and angel content of 40 % or above, which is copolymerized with 30 ton70 % by weight of rubber with a glass transition temperature lessnthan 10°C, 20 to 55 % by weight of at least one organic materialnselected from the group consisting of styrene, α-substitutednstyrene and nucleus-substituted styrene, 5 to 25 % by weight ofnacrylonitrile and 0 to 20 % by weight of methylmethacrylate,n(B) 5 to 20 parts by weight, per 100 parts by weight of the basenresin(A), of a phosphorous blend of triarylphosphates andnoligomeric phosphates, or of a synthetic oligomeric phosphate, andn(C) 0.1 to 2.0 parts by weight, per 100 parts by weight of thenbase resin(A), of a perfluoroalkane polymer. |
