摘　　要：采用两步合成法合成出聚叠氮缩水甘油醚(GAP).首先以乙二醇为引发剂,用阳离子催化剂对环氧氯丙烷进行开环聚合,合成聚环氧氯丙烷(PECH);然后采用大分子基团取代的方法,让PECH和NaN3在非质子极性溶剂DMSO中反应合成叠氮粘合剂GAP.采用红外光谱(FTIR)对PECH,GAP的结构进行了分析,并对GAP的数均分子量、官能度以及热分解特性进行了测试.结果表明:合成出的GAP数均分子量为5 013,官能度为3.59,最大热分解放热峰温为250.5℃.GAP分子量较高,官能度较大,分解峰温高,热稳定性较好,是研究高能低特征信号推进剂的理想材料.Glycidyl Azide Polymer （GAP） was synthesized by the two-step synthesis method. Firstly, with ethylene glycol as initiator and cationic catalyst, polyepichlorohydrin（PECH） was synthesized by the opening-ring polymerization of epichlorohydrin. Then, using the macromolecules method, GAP was synthesized by the reaction of PECH and NaN3 in the polar aprotic solvents DMSO. The FTIR was employed to measure and analyze the structure of PECH and GAP, and molecular weight, functionality, and thermal decomposition characteristic were characterized. The results show that molecular weight of GAP is 5 013, functionality is 3.59, the exothermic decomposition of GAP is 250.5℃. If Molecular weight, functionality, and decomposition peak temperature is higher, thermal stability is better. GAP is the ideal material for the high energy and low characteristic signal propellant.
