Patent ID: 8071694

Claim:
A thermoplastic composition comprising: a mixture of i) from 10 to 98 weight % of a polycarbonate polymer, wherein the polycarbonate polymer is an aromatic polymer or an alicyclic polymer; ii) from 2 to 90 weight % of a polyester polymer comprising structures derived from a diol compound having the structure (A) HOâ€”Zâ€”OH, wherein Z is a C 4 to C 36 linear aliphatic radical, a C 3 to C 36 branched aliphatic or cycloaliphatic radical, a C 6 to C 36 aryl radical, or a C 7 to C 36 alkylaryl radical, and a diacid compound having the structure (B) HOOCâ€”CH 2 CH 2 â€”COOH, and iii) a polylactic acid polymer, wherein the polylactic acid polymer is present in an amount of up to 5 wt %; wherein the sum of the polycarbonate polymer, the polyester polymer, and the polylactic acid polymer is equal to 100 weight %.
