In a polycarbonate resin composition containing a polycarbonate resin and a polycarbosilane compound, the use of the polycarbosilane compound modifies the surface properties of the polycarbonate resin composition without adversely affecting the intrinsic characteristics of the polycarbonate resin, such as transparency, heat resistance, and mechanical properties, e.g., impact resistance. A polycarbonate resin composition containing 100 parts by mass of a polycarbonate resin, 0.001 to 1 part by mass of a metal salt compound, and 0.005 to 5 parts by mass of a polycarbosilane compound has significantly improved flame resistance and high transparency and causes markedly reduced outgassing and mold fouling, without losing impact resistance and heat resistance.
在含有聚碳酸酯树脂和聚碳硅烷化合物的聚碳酸酯树脂组合物中,使用聚碳硅烷化合物可以改变聚碳酸酯树脂组合物的表面特性,而不会对聚碳酸酯树脂的固有特性产生不利影响,如透明度、耐热性和机械性能(例如冲击强度)。含有100质量部聚碳酸酯树脂、0.001至1质量部金属盐化合物和0.005至5质量部聚碳硅烷化合物的聚碳酸酯树脂组合物具有显著提高的阻燃性和高透明度,显著减少气体排放和模具污染,同时不会损失冲击强度和耐热性。
