摘要： A process for dispersing one or more powdered ignition resistant or flame retardant additives into carbonate polymers which comprises the steps of preparing a base concentrate having about 5 to about 50 weight per cent of said additives by blending said additives with a carbonate polymer having a melt flow rate from about 3 to about 20, pelletizing said base concentrate having said ignition resistant additive dispersed therein, dry blending said concentrate pellets with carbonate pellets having a melt flow rate from about 1 to about 80 whereby said polymer/concentrate blend has an amount of said additive dispersed therein effective to render said blend ignition resistant, and pelletizing or molding said carbonate polymer/concentrate blend. The use of this method gives ignition resistant carbonate polymers with improved impact properties as measured by Izod impact tests.

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.
