ABSTRACT:
Blends of polysulfones, polyethersulfones and polyphenylene ether sulfones with resorcinol based polyesters, or resorcinol based polyester carbonate polymers, and silicone copolymers have improved flame resistance. Peak heat release energy is reduced and the time to reach peak heat release is increased.
