Blends of siloxane copolymers, notably siloxane polyimides, with polyaryl esters or polyaryl ester carbonates containing linkages derived from resorcinol, show improved flame resistance, as measured by two minute and peak heat release, compared to conventional polycarbonates. In some instances transparent flame retardant blends can also be prepared. The compositions show good melt processability, high impact strength and high elongation, and can be used to make various flame retardant articles including sheets and films.
硅氧烷共聚物,特别是硅氧烷聚酰亚胺,与含有间苯二酚链节的聚芳基酯或聚芳基酯碳酸盐的混合物,与传统的聚碳酸酯相比,通过两分钟和峰值热释放测量,显示出更好的阻燃性。在某些情况下,还可以制备透明的阻燃混合物。这些组合物具有良好的熔融加工性、高冲击强度和高伸长率,可用于制造各种阻燃制品,包括板材和薄膜。
