Abstract The polycarbonates prepared by phosgenation of bis(4-hydroxyphenyl)phenylmethane (BHPM) or bis(4-hydroxyphenyl)diphenylmethane (BHDM) were characterized by inherent viscosity measurements, infra-red spectroscopy, differential scanning calorimetry and thermogravimetric analysis. The polycarbonate of BHDM showed a significantly higher glass transition temperature as well as polymer decomposition temperature than the BHPM polycarbonate. Several physical and thermal characteristics of these polymers were correlated with their chemical structure.

双(4-羟基苯基)苯基甲烷和双(4-羟基苯基)二苯基甲烷的聚碳酸酯

摘要 对双（4-羟基苯基）苯基甲烷（BHPM）或双（4-羟基苯基）二苯基甲烷（BHDM）光气化制备的聚碳酸酯通过特性粘度测量、红外光谱、差示扫描量热法和热重分析进行了表征。BHDM 的聚碳酸酯显示出比 BHPM 聚碳酸酯显着更高的玻璃化转变温度和聚合物分解温度。这些聚合物的一些物理和热特性与其化学结构相关。
