摘要：
A composition comprises a polyester-polycarbonate polymer comprising isophthalate-terephthalate-resorcinol ester units and carbonate units, a first polyester selected from poly(ethylene terephthalate), poly(ethylene isophthalate), or a combination thereof, and a second polyester comprising butylene terephthalate units, cyclohexanedimethylene terephthalate units, or a combination of cyclohexanedimethylene terephthalate units and ethylene terephthalate units. 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.
