Flame-retardant PC/ABS compounds with good impact strength, flowability and chemical resistance

摘要

Flame-retardant, thermoplastic molding composition comprises: (a) at least one aromatic polycarbonate (50-90 parts by weight); (b) at least one graft polymer (4-14 parts by weight); (c) at least one vinyl (co)polymer (0-15 parts by weight); (d) at least one phosphorus-containing flame retardant (1-20 parts by weight); (e) at least one rubber-free anhydride-modified alpha -olefin terpolymer (0.5-5 parts by weight); (f) at least one filler (0-25 parts by weight); and (g) other conventional additives (0-10 parts by weight), where sum of parts by weight of components (a)-(f) is 100 parts by weight. An independent claim is also included for a flame retardant polycarbonate/acrylonitrile butadiene styrene polymer blend comprising an ethylene-propylene-octene-maleic anhydride copolymer.
