Polyetherimide-polyarylate, blends

Abstract

Disclosed are blends of (a) a polyetherimide and (b) a polyarylate, an aromatic polyester which is derived from a dihydric phenol and a dicarboxylic acid. These blends have improved flexural strength and flexural modulus over the polyarylate component alone and have a higher impact strength than that associated with the polyetherimide component of the blends. In addition, the blends exhibit improved molding performance characteristics as evidenced by a lower molding pressure being required than that necessary for either component of the blend when molded alone.

Dependencies are inferred from the claim text.
