    • The above-described and other deficiencies of the art are met by a method of making a polycarbonate polymer comprising isosorbide carbonate units, comprising melt reacting a dihydroxy compound comprising an isosorbide of the general formula: O O H H HO OH, and an activated carbonate, in the presence of a catalyst consisting essentially of a sodium salt capable of providing a hydroxide ion, wherein the polycarbonate polymer comprises greater than or equal to 50 mol% isosorbide carbonate units, and wherein the polycarbonate polymer has a Mw of greater than or equal to about 40,000 g/mol as determined by gel-permeation chromatography relative to polystyrene standards. Polycarbonates comprising the isosorbide carbonate unit, including isosorbide homopolycarbonate and an isosorbide-based polyester- polycarbonate, are also disclosed, as are a thermoplastic composition and an article including the isosorbide-based polycarbonate polymer.
    • 本领域的上述和其它缺陷通过制备包含异山梨醇碳酸酯单元的聚碳酸酯聚合物的方法来实现,该方法包括使包含通式为:OHOH的异山梨醇和活化的碳酸酯的二羟基化合物与活化的碳酸酯熔融反应, 存在基本上由能够提供氢氧根离子的钠盐组成的催化剂,其中聚碳酸酯聚合物包含大于或等于50摩尔%的异山梨醇碳酸酯单元,并且其中聚碳酸酯聚合物的Mw大于或等于约40,000 通过凝胶渗透色谱法相对于聚苯乙烯标准物测定。 还公开了包含异山梨醇碳酸酯单元的聚碳酸酯,包括异山梨醇均聚碳酸酯和异山梨醇基聚酯 - 聚碳酸酯,热塑性组合物和包含异山梨醇基聚碳酸酯聚合物的制品也是公开的。
