Abstract
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.
