Abstract (en)

[origin: WO9957198A1] A thermoplastic resin composition that contains an aromatic polycarbonate resin, a rubber modified graft copolymer comprising a discontinuous elastomeric phase dispersed in a continuous rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is chemically grafted to the elastomeric phase, a phosphorus containing flame retardant compound, and a fluoropolymer, in an amount effective to improve the flame retardant performance of the composition, provided that the fluorine content of the composition does not exceed 0.1 percent by weight fluorine.
