CAMERA LENSES PREPARED FROM THERMOPLASTIC COMPOSITIONS HAVING HIGH FLOW AND DUCTILITY, AND METHOD OF PREPARING CAMERA LENSES

摘要

Disclosed herein is a camera lens comprising a thermoplastic composition comprising a poly(aliphatic ester)-polycarbonate copolymer comprising soft block ester units derived from an alpha, omega C6-20 aliphatic dicarboxylic acid or derivative thereof, a dihydroxyaromatic compound, and a carbonate source, wherein the thermoplastic composition has a melt volume rate of 13 to 25 cc/10 min at 250° C. and under a load of 1.2 Kg and a dwell time of 6 minutes, according to ASTM D1238-04, and wherein the camera lens has an effective lens area of 0.5 to 100 mm2. A method of making the camera lens, and a camera lens comprising a thermoplastic composition comprising a redistribution product of a poly(aliphatic ester)-polycarbonate, are also disclosed.
