摘 要:通过熔融酯交换法,以碳酸二苯酯、双酚A、双醚芴为单体,调节醇酯比设计产物端基结构,合成出一系列结构相近、数均分子量相近的双醚芴型聚碳酸酯,并通过红外光谱、核磁共振氢谱验证了产物的三单体共聚结构,通过凝胶渗透色谱检测了产物分子量和多分散性。该碳酸酯具有较高的玻璃化转变温度,最高可达155℃,热分解速率最快所对应的温度区间为160~200℃,起始分解温度360℃,最快分解温度为378℃,分解反应活化能为133~274 kJ·mol^(-1)。A series of bisetherfluorene polycarbonates with similar structure and similar molecular weight were synthesized from diphen-yl carbonate,bisphenol A,bietherfluorene by melting transesterification method;the trimonomeric copolymerization structure of the product was verified by infrared spectroscopy and nuclear magnetic resonance hydrogen spectroscopy;the molecular weight and polydis-persity of the product were detected by gel permeation chromatography.The product has a high glass transition temperature up to 155℃,the temperature range of the fastest thermal decomposition rate was 160~200℃,the initial decomposition temperature was 360℃,the fastest decomposition temperature was 378℃,and the activation energy of the decomposition reaction was 133~274 kJ·mol^(-1).
