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.

摘要： Blends of carbonate and monovinylidene aromatic copolymers containing selected low molecular weight halogenated epoxy compounds, in combination with tetrafluoroethylene polymers, are shown to have surprising combinations of impact and ignition resistance and be very suitable for electroplating applications. In general the selected epoxy compounds can be represented by the following formula: ##STR1## where, preferably, R is hydrogen; X is bromine; i is 2; L is 2,2-isopropyl; n is from 0 to 1. Polymer blends based on from about 65 to about 98 weight percent carbonate polymer, from about 2 to about 25 percent by weight monovinylidene aromatic copolymer, preferably rubber modified, and from 0 to about 10 percent by weight of a rubbery core/shell graft copolymer impact modifier are suitable for preparation of these compositions. It has been found desirable to employ from about 1 to about 20 percent by weight low molecular weight halogenated epoxy compound, and from 0.01 to about 2 percent by weight of a tetrafluoroethylene polymer.
