Abstract:
1. A composition comprising from 1 to 90 weight percent of a polyester-polycarbonate polymer of the formula wherein each R is independently a halogen atom, a C 1-12 hydrocarbon group, or a halogen-substituted C 1-12 hydrocarbon group, p is 0 to 4, m and n are each 2 to 500, and each R 1 is independently a C 6-30 aromatic hydrocarbon group; from 1 to 90 weight percent of poly(ethylene terephthalate), poly(ethylene isophthalate), or a combination thereof, as a first polyester; from 1 to 90 weight percent of a second polyester comprising butylene terephthalate units, cyclohexanedimethylene terephthalate units, or a combination of 10 to 30 mole percent ethylene terephthalate units and from 70 to 90 mole percent 1,4-cyclohexanedimethylene terephthalate units; wherein all weight percents are based on the total weight of the composition, and wherein an article molded from the composition has a percent haze value of less than or equal to 10 percent, and a total luminous transmittance value of greater than or equal to 70 percent, each measured according to ASTM D1003-00.
