Abstract:
A thermoplastic resin composition containing(A) 40 to 95 parts by weight of a halogen-free, thermoplastic polycarbonate; (B) 5 to 50 parts by weight of a styrene-containing graft copolymer prepared by grafting (B-1) onto (B-2) (B-1) 5 to 95% by weight, based on (B), of a mixture of (B-1.1) 50 to 100% by weight of styrene, &agr;-methyl styrene, nucleus-substituted styrene, methyl methacrylate or a mixture thereof, and (B-1.2) 50 to 0% by weight of acrylonitrile, methacrylonitrile, C1-C8 alkyl methacrylate, C1-C8 alkyl acrylate, alkyl acrylate, maleic anhydride, N-substituted maleimide or a mixture thereof (B.2) 95 to 5% by weight, based on (B), of a rubber with a glass transition temperature (Tg) of below Ëœ10 Â° C. and selected from the group consisting of butadiene rubbers, acryl rubbers, ethylene/propylene rubbers, styrene/butadiene rubbers, acrylonitrile/butadiene rubbers, butadiene/styrene rubbers, polyisoprene, EPDM rubbers, polyorganosiloxane, and mixtures thereof; (C) 0 to 30 parts by weight of a styrene containing copolymer prepared from (C-1) 50 to 95% by weight of styrene, &agr;-methyl styrene, nucleus-substituted styrene, methyl methacrylate or a mixture thereof, and (C-2) 50 to 5% by weight of acrylonitrile, C1-C8 alkyl methacrylate, C1-C8 alkyl acrylate, or a mixture thereof; (D) 5 to 20 parts by weight, based on 100 parts by weight of (A)+(B)+(C), of a mixture comprising (D-1) 100 to 5 % by weight of a mixture of alkyl substituted monophosphate esters of the formula(I) â€ƒin which, R is an alkyl group selected from the group consisting of t-butyl, isopropyl, isobutyl, isoamyl, and t-amyl, and N is an integer from 1 to 3; and (D-2) 0 to 95 % by weight, of phosphate esters of the formula (II) â€ƒin which, R1, R2, R4, and R5 are independently cresyl, phenyl, xylenyl, propylphenyl, butylphenyl, or brominated or chlorinated derivatives thereof, R3 is an arylene group, and M is 0 to 5; and E) 0 to 2 parts by weight, based on 100 parts by weight of(A)+(B)+(C), of a fluorinated polyolefin polymer.
