摘　　要：合成了偶氮苯生色分子4-羟基-4'-偶氮苯甲酸,采用自由基聚合法将生色分子与环氧氯丙烷和α-甲基丙烯酸反应,合成了含偶氮支链的聚电解质(APE)。利用傅里叶红外光谱(FT-IR)、紫外-可见光谱(UV-V is)等分析手段对中间产物和APE进行了结构表征。采用差示扫描量热分析仪(DSC)对APE进行了热稳定性表征,其玻璃化转变温度(Tg)为189.7℃,表明具有较好的热稳定性。Chromophore containing azobenzene, 4 -hydroxy -4＇-azo benzoic acid was synthesized. A branched side- chain azobenzene polyelectrolyte （APE） was synthesized with chromophore, epoxy chloropropane and α- methacrylic acid by free radical polymerization. The chemical structures of intermediate products and APE were characterized by FT - IR and UV - Vis spectroscopy. The thermal property of APE was characterized using the differential scanning calorimeter （DSC）. The glass transition temperatures （Tg） was 189.7℃, respectively. The result showed that the APE had excellent thermal stability.
