High impact polystyrene containing halophenoxyalkylsilane flame retardant

摘要

A flame retarded high impact polystyrene composition having improved izod impact strength. The high impact polystyrene composition of the present invention contains a flame retardant amount of a halophenoxyalkylsilane. The preferred halophenoxyalkylsilane is bis-(2,4,6-tribromophenoxy)dimethylsilane. Antimony oxide may optionally be present.
