    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.

    摘要: Thermoplastic resins of enhanced solvent resistance especially useful for packaging or automotive parts comprising blends of amorphous polyamides with a thermoplastic polyester resin, substantially free of a polyarylate have excellent physical properties and barrier resistance to oxygen and carbon dioxide. Preferred blends comprise polyesters prepared by reacting a dihydric alcohol with a dicarboxylic acid, and amorphous polyamides prepared from non-symmetric monomers comprising odd-number chain diamines and diacids, and meta aromatic diamines and diacids.

    摘要: An aromatic polyphthalatecarbonate resin having a small percentage of phthalate units therein exhibits improved resistance to hazing and yellowing upon exposure to ultraviolet radiation. The polyphthalate carbonate resin is derived from the reaction products of a phthalate compound, a dihydric phenol and a carbonate precursor.

    摘要: A process for making polyetherimides involving reacting an aromatic bis(ether anhydride) with an organic diamine in the presence of a solvent so as to form a polyamide acid. The polyamide acid is thereafter polymerized in a solid state at a temperature below the glass transition temperature of the final polyetherimide.
