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 and boron trifluoride etherate as catalyst, epichlorohydrin was subjected to ring-opening polymerization to obtain epichlorohydrin homopolymer (PECH) with chloromethyl group at one end and hydroxyl group at the other end. ; Then, using N-methylimidazole as a catalyst, one end of the PECH is esterified with hydroxyl groups to terminal acetate PECH (AT-PECH) by acetic anhydride; finally, azide is used to form an azido ethyl group at one end and the other end Acetate-based azide glycidyl ether polymer (AATGAP). The structure and properties of AATGAP were studied by FTIR, DSC and TGA. AATGAP glass transition temperature of -74.5 ℃, thermal decomposition temperature of 250.08 ℃, low viscosity, can be used as a plasticizer containing energy.
