Laminate compositions with polyarylate and poly(aryl ether)

Abstract From the Canadian patent

Described herein are laminate compositions comprising a polyarylate, or blends thereof derived, from a dihydric phenol and an aromatic dicarboxylic acid which is laminated upon the surface of a poly(aryl ether), particularly polysulfone. In contrast to the highly ultraviolet sensitive polysulfone, the laminate compositions of this invention exhibit good weatherability including no a?verse effects, e.g. degradation, from prolonged ultraviolet irradiation exposure. The laminate compositions of this invention have beneficial utility in solar energy applications.
