Abstract
Weatherability of polycarbonates, or of blends of polycarbonates with other polymers such as polyesters, is improved by incorporating therein a thermoplastic arylate polymer comprising units derived from a resorcinol or alkylresorcinol isophthalate-terephthalate. These units may be combined with units derived from a resorcinol or alkylresorcinol ester of a C.sub.4-12 aliphatic, alicyclic or mixed aliphatic-alicyclic dicarboxylic acid, such as sebacic acid.
