| 摘 要： | 以1，4-丁二醇为引发剂，三氟化硼乙醚络合物为催化剂，使环氧氯丙烷发生开环聚合制得环氧氯丙烷均聚物（PECH），PECH经叠氮化形成端羟基叠氮基缩水甘油醚聚合物（GAP），然后再以1-甲基眯唑为催化剂，用乙酸酐将GAP酯化成端乙酸酯基GAP（ETGAP）。用FT—IR、DSC等方法研究了ETGAP的结构和性能。ETGAP的玻璃化转变温度为-65．36℃，热分解温度为251．02℃，黏度小，可用作含能增型剂。

| Abstract: | Polyepichlorohydrin(PECH) was synthesized by the opening-ring polymerization of epichlorohydrin using 1,4-butanediol as initiator,boron-trifluoride etherate as catalyst.Hydroxyl-terminated glycidyl azide polymer(GAP) was synthesized by azidation of PECH,and then acetate-terminated glycidyl azide polymer(ETGAP) was obtained by the reaction of GAP with acetic anhydride using 1-methyl imidazole as catalyst.The structure and performance of ETGAP were studied by FTIR and DSC.The ETGAP glass transition temperatur... |
