Patent ID: 8222347

Claim:
A composition comprising a thermoplastic resin composition derived from (a) a polyester consisting of units of at least one cycloaliphatic diol, aromatic diacid, and optionally an additional diol, wherein the at least one cycloaliphatic diol comprises cyclohexane dimethanol and wherein the at least one cycloaliphatic diol and the additional diol are not tetramethyl cyclobutane diol; (b) a polycarbonate polymer derived from (i) at least from 20 mole percent to 50 mole percent of an aromatic diol derived from structure II wherein R 3 and R 4 are independently selected from the group consisting of C 1 -C 30 aliphatic, C 2 -C 30 cycloaliphatic and C 2 -C 30 aromatic groups, X is CH 2 and m is an integer from 3 to 7, n is an integer from 1 to 4, p is an integer from 1 to 4 and (ii) from 50 mole percent to 80 mole percent of a second aromatic dihydroxy compound; and (c) optionally, a thermoplastic resin C, different from the polyester and the polycarbonate polymer, that is selected from the group consisting of homopolycarbonate, a poly(estercarbonate), a poly(arylatecarbonate) and combinations thereof; wherein the thermoplastic resin composition is transparent and has a transmission of at least 70% and a haze less than 10%.
