  摘要：

  这项工作通过双酚 A 二乙酸酯与亚烷基和亚芳基二苯基二碳酸酯的熔融缩聚，提出了一种合成芳香族和脂肪族聚碳酸酯的新方法。二碳酸二苯酯由氯甲酸苯酯和相应的二羟基化合物制备。该方法包括在干燥氩气缓慢流下的预缩合步骤，同时去除乙酸苯酯，然后在高温和真空下进行熔融缩聚。该反应的潜力通过一系列具有 0.19 至 0.43 dL/g 特性粘度的芳香族-芳香族和芳香族-脂肪族聚碳酸酯的成功合成得到证明。因此获得低至中等分子量的聚合物。碳酸酯基团碳的 (13)C-NMR 谱表明，形成的聚碳酸酯在其链中含有部分随机序列分布的单体残基。聚碳酸酯通过特性粘度、FTIR、(1)H-NMR和(13)C-NMR光谱表征。通过 DSC 测得的聚碳酸酯的玻璃化转变温度在 13-108 摄氏度之间。 热重曲线表明这些聚合物在高达 250 摄氏度时具有良好的热稳定性。本方法可能为新型聚碳酸酯打开大门含有其他有机官能团。

  Poly(ether sulfones) (PES) and poly(ether amide sulfones) (PEAS) were prepared from post-consumer polycarbonates and polyesters, respectively, using a single vessel in batch mode (all reactants present when heating was initiated). The depolymerization of the initial polymer occurs concurrently with step growth polymerization to form a product polymer having a number average molecular weight of at least 5000.
