ATGAP的合成与性能

Synthesis and Properties of Azido Terminated Glycidyl Azide Polymer

以1,4-丁二醇为引发剂,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环氧氯丙烷均聚物(PECH)。采用磺酸酯法,首先PECH与对甲苯磺酰氯在吡啶介质中反应形成端磺酸酯基氯化聚醚中间体(T sPECH),然后中间体经叠氮化作用形成端基为叠氮基的叠氮缩水甘油醚聚合物(ATGAP)。用红外、核磁、碳谱研究化合物的结构。结果表明,所得产物是目标聚合物,ATGAP的玻璃化转变温度为-73℃,热分解温度为252.7℃,黏度小,可以作为含能增塑剂使用。

Using 1,4-butanediol as initiator, boron-trifluoride etherate as catalyst, polyepichlorohydrin （PECH） was synthesized by the opening-ring polymerization of epichlorohydrin. Using the method of tosylation, tosylate terminated epichlorohydrin polymer as intermediate was synthesized by PECH and 4 toluenesulfonylzchloride in pyridine, azido terminated glycidyl azide polymer （ATGAP） was obtained by the reaction of intermediate and sodium azide. The structure of ATGAP was characterized by IR, ^1HNMR and ^13CNMR, showing that the final product was target product . The glass transition temperature of ATGAP was -73℃. Its thermal decomposition temperature was 252.7℃. ATGAP has small viscosity and can be used as an energetic plasticizer.
