摘　　要：以2-氯乙醇为引发剂,三氟化硼乙醚络合物为催化剂,环氧氯丙烷发生开环聚合得到一端为氯甲基、另一端为羟基的环氧氯丙烷均聚物(PECH);然后,以N-甲基咪唑为催化剂,乙酸酐将PECH的一端羟基酯化成端乙酸酯基PECH(AT-PECH);最后,经叠氮化作用形成一端为叠氮乙基、另一端为乙酸酯基的叠氮缩水甘油醚聚合物(AATGAP)。用FTIR、DSC、TGA等方法,研究了AATGAP的结构和性能。AATGAP的玻璃化温度为-74.5℃,热分解温度为250.08℃,粘度小,可作为含能增塑剂使用。Using 2-chloroethanol as initiator, boron-trifluoride etherate as catalyst, polyepichlorohydrin comprising an chlorom- ethyl terminal group and an hydroxyl terminal group was synthesized by the opening-ring polymerization of epichlorohydrin. Then, using N-methyl imidazole as catalyst, acyloxy terminated polyepichlorohydrin （ATPECH）was obtained by the reaction of C1PECH and acetic anhydride. Finally, glycidyl azide polymer comprising an azide terminal group and an acyloxy terminal group（AATGAP） was synthesized by azidation of ATPECH, and was characterized by FTIR, DSC and TGA. With the glass transition temperature of -74.5℃ and thermal temperature of 250.08℃, AATGAP can be used as engergetic plasticizer.
