Abstract:
1. A composition comprising a miscible polymer blend of: a) a resin selected from the group consisting of resorcinol based polyester carbonates, resorcinol based polyarylates and mixtures thereof, b) at least one alkyl amide compound with a molecular weight from 250 to 1000 and c) one or more polyimide resins, wherein said polyester carbonates and polyarylates have at least 50 mole % aryl ester linkages derived from resorcinol, and wherein the miscible polymer blend has a percent transmission, as measured at 3.2 mm, using ASTM method D1003, of greater than or equal to 50%; wherein the alkyl amide mold release agent is selected from the structures shown below: wherein R wherein the refractive index, as measured by ASTM method D542, is from about 1.580 to about 1.680.
