ABSTRACT:
The present invention relates to a polymer composition comprising a transparent polymer blend. The polymer blend comprises a first resin and a second resin. The first resin comprises polyarylate structural units of formula I, wherein R1is independently at each occurrence a C1–C2alkyl group, or a halogen atom, and p is 0 to 3. The second resin is selected from the group consisting of polycarbonates, polyarylates and copolyestercarbonates. The first resin and the second resin are further characterized by a difference in polyarylate structural unit content, said difference being less than about 40 mole percent.
