Abstract
Flame retardant blends of an aromatic polycarbonate, preferably a tetraalkylsubstituted aromatic polycarbonate, and a copolymer of an alkenyl aromatic compound and a halogenated alkenyl aromatic compound are described. The ultraviolet light resistance and impact strength of articles molded from such compositions is superior to that of moldings prepared from corresponding blends of the polycarbonate, a polystyrene homopolymer and a conventional low molecular weight halogenated flame retardant agent.
