Abstract:
A thermoplastic resin composition, comprising:(a) an aromatic carbonate resin,(b) 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, wherein the rubber phase of the copolymer is made by an aqueous emulsion polymerization in the presence of a (C.sub.30 -C.sub.108) polyacid surfactant, and(c) a flame retarding amount of an organophosphorus flame retardant comprising one or more compounds according to the structural formula (VI): ##STR7## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each independently aryl, which may be optionally substituted with halo or alkyl,X is arylene, optionally substituted with halo or alkyl,a, b, c and d are each independently 0 or 1, andn is an integer from 1 to 5.
