    • A composition comprises a polyester-polycarbonate polymer comprising isophthalate-terephthalate-resorcinol ester units and carbonate units, a first polyester comprising repeating units derived from cyclohexane dicarboxylic acid or a chemical equivalent thereof, and a C2-8 aliphatic diol or a chemical equivalent thereof, and a second polyester comprising units derived from isophthalic and/or terephthalic acid and a chemical equivalent thereof, and a C2-8 aliphatic diol or a chemical equivalent thereof. The composition can be extruded into pellets that are clear and colorless. The composition can further be molded into articles having a percent haze value less than or equal to 10 percent, and total luminous transmittance value of greater than or equal to 70 percent, measured in accordance with ASTM D1003-00. Also disclosed is a method for forming the compositions, and articles prepared therefrom.
    • 组合物包含含有间苯二甲酸酯 - 对苯二甲酸酯 - 间苯二酚酯单元和碳酸酯单元的聚酯 - 聚碳酸酯聚合物,包含衍生自环己烷二羧酸或其化学等价物的重复单元的第一聚酯,以及C 2-8脂族二醇或其化学等价物, 和包含衍生自间苯二甲酸和/或对苯二甲酸及其化学等价物的单元的第二聚酯,以及C 2-8脂族二醇或其化学等价物。 该组合物可以挤出成清澈无色的颗粒。 根据ASTM D1003-00测量,该组合物可以进一步模制成具有小于或等于10%的雾度百分比值和大于或等于70%的总光透射率值的制品。 还公开了形成组合物的方法和由其制备的制品。
