A composition comprising an admixture of a). an aromatic polycarbonate of intrinsic viscosity of from about 0.35 to about 0.41 dl/g, measured in methylene chloride at about 25 DEG C, said aromatic polycarbonate chain terminated with an endcapping agent which provides the polycarbonate with improved ductility and higher Tg when compared to a paratertiary butyl phenol encapped polycarbonate of the same intrinsic viscosity; b).a core/shell copolymer comprising a conjugated diene with a Tg of less than or equal to -10 DEG C as the core, said core being about 50 to 90 wt. percent of the core/shell polymer, and grafted thereon a shell comprised of an alkylalkacrylate and a styrenic, the core/shell copolymer present in such quantities to render the said composition ductile in the room temperature 1/8 inch thickness Notched Izod test system under ASTM D-256, and c). a flame retardant combination comprising a flame retardant salt, said combination in quantities sufficient to achieve a UL-94 V-0 or V-1 rating in a molded part 90 mils thick. a |
