CYCLOALIPHATIC POLYESTER COPOLYMER ARTICLES AND METHODS FOR MAKING ARTICLES THEREFROM

摘要

A thermoformable sheet can comprise: a cap layer comprising a combination of a bisphenol cyclohexylidene polycarbonate and a cycloaliphatic polyester copolymer, and a base layer comprising polycarbonate. A method for making an article can comprise: melting a polycarbonate in an extruder, forming a molten combination of a bisphenol cyclohexylidene polycarbonate and a cycloaliphatic polyester copolymer, and coextruding the molten combination and the polycarbonate to form a sheet.
