ABSTRACT:
Disclosed is a thermoplastic composition comprising a mixture of from 10 to 98 weight % of a polycarbonate polymer, from 2 to 90 weight % of a polyester polymer comprising structures derived from a diol compound having the structure (A) HO—Z—OH, wherein Z is a C1to C36linear aliphatic radical, a C3to C36branched aliphatic or cycloaliphatic radical, a C6to C36aryl radical, or a C7to C36alkylaryl radical, and a diacid compound having the structure (B) HOOC—CH2CH2—COOH, from 0 to 5 weight % of a polylactic acid polymer, wherein the sum of the polycarbonate polymer, the polyester polymer, and the polylactic acid polymer is equal to 100 weight %. The thermoplastic composition has improved mechanical properties.
