摘要: According to the present invention there are obtained improved ignition resistant carbonate polymer blends having unexpectedly better combinations of toughness, ignition resistance, processability and stability. In particular the blend comprises a major amount of carbonate polymer, a minor amount of a rubber-modified monovinylidene aromatic copolymer, and an optional rubbery core/shell graft copolymer impact modifier. As ignition resistance additives the blends contain a metal salt of an aromatic sulfur compound, a buffering aromatic sulfur compound, an organophosphorus compound, and a tetrafluoroethylene polymer.
