摘要： Disclosed herein is a flame retardant composition comprising 10 to 90 weight percent of a linear polycarbonate; a branched polycarbonate; 10 to 70 weight percent of a polysiloxane-polycarbonate copolymer where the polysiloxane-polycarbonate copolymer comprises 10 weight percent or less of polysiloxane having a weight average molecular weight of less than 30,000 Daltons; and 1 to 20 weight percent of a phosphazene compound; were all weight percents are based on the total weight of the composition, and where the composition does not contain a flame retardant other than the phosphazene compound. Disclosed herein too is a method comprising blending 10 to 90 weight percent of a linear polycarbonate; a branched polycarbonate; 10 to 70 weight percent of a polysiloxane-polycarbonate copolymer where the polysiloxane-polycarbonate copolymer comprises 10 weight percent or less of polysiloxane having a weight average molecular weight of less than 30,000 Daltons; and 1 to 20 weight percent of a phosphazene compound; to form a flame retardant composition; were all weight percents are based on the total weight of the composition, and where the composition does not contain a flame retardant other than the phosphazene compound.
摘要翻译：本文公开了包含20至80重量％的聚碳酸酯组合物的阻燃剂组合物; 其中聚碳酸酯组合物包含聚硅氧烷 - 碳酸酯共聚物; 抗冲改性剂，其量为0.5至25重量％; 和1-20重量％的磷腈化合物; 其中所有重量百分比都基于阻燃剂组合物的总重量。本文还公开了一种方法，其包括共混20至80重量％的聚碳酸酯组合物; 其中聚碳酸酯组合物包含聚硅氧烷 - 碳酸酯共聚物; 抗冲改性剂，其量为0.5至25重量％; 和1-20重量％的磷腈化合物以生产阻燃剂组合物; 其中所有重量百分数均基于阻燃剂组合物的总重量; 并挤出并模塑阻燃组合物。
