Abstract
Disclosed are ternary blends of (a) a polyetherimide and (b) a polyarylate, an aromatic polyester which is derived from a dihydric phenol and a dicarboxylic acid and (c) a thermoplastic polymer selected from polycarbonates and aliphatic-aromatic polyesters which is compatible with the polyetherimide and the polyarylate. The blends exhibit a high heat distortion temperature and have a good degree of flame resistance.
Claims14
A composition comprising a blend of (a) a polyarylate which is derived from at least one dihdyric phenol and at least one aromatic dicarboxylic acid, (b) a polyetherimide and (c) a thermoplastic polymer which is compatible with the blend of the polyarylate and the polyetherimide.
