Zusammenfassung:The invention relates to flame retardant polycarbonate resin/ABS graft copolymer blends that exhibit improved performance. A thermoplastic resin composition contains an aromatic carbonate resin, a rubber modified graft copolymer comprising a discontinuous rubber phase dispersed in a continuous rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is chemically grafted to the rubber phase, and a flame retarding amount of an alkali metal or alkaline earth metal salt of an alkylbenzenesulfonic acid flame retardant.
