Synthesis of polyarylate containing phthalazinone moiety and its application in insulating varnish

以二酸4-[4-(4-羧基苯氧基)苯基]-2-(4-羧基苯基)二氮杂萘-1-酮(Ⅰ)与4,4'二羟基二苯丙烷进行溶液缩聚反应合成了一种含有二氮杂萘酮结构的聚芳酯,采用FT-IR,1H NMR对其结构进行了表征,利用差示扫描量热仪(DSC),热重分析仪(TGA)研究了聚芳酯的热性能.结果表明所合成的聚芳酯具有高的玻璃化转变温度(227℃),在氮气气氛中5%的热失重温度高于455℃.聚芳酯可溶解于N-甲基吡咯烷酮(NMP),N,N-二甲基乙酰胺(DMAc),氯仿等多种溶剂,该类聚芳酯制成的绝缘漆,具有机械强度高,柔韧性和附着力好,以及良好的电绝缘性能.
