摘要：
Novel copolymers are prepared by the interaction of low or high molecular weight polyarylates, such as bisphenol A-isophthalate-terephthalate polyarylates, or bisphenol A-isophthalate-terephthalate-carbonate polyarylates and a high molecular weight diprimary dialcohol polyester polymer, such as polyethylene terephthalate polymer. The resulting copolymers are transparent and tough. They maintain their dimensional stability over a wide range of temperature from 75.degree.-175.degree. C., are soluble in chlorinated solvents, and have one glass transition point.
