With trimethyl,4-dodecylbenezyl ammonium chloride and 18-crown-6 as pase-transfer catalysts, the azidation of polyepichlorohydrin in poly and H2O were studied. The reaction discipline and mechanism were discussed. The results show that the system with trimethyl, 4-dodecylbenezyl ammonium chloride as phase transfer catalyst and PEG as medium is a safe and effective approach to glycidyl azide polymer preparation, and azidational ratio of PECH can reach 97% above within 15 h.

研究了氯化十二烷基苄基三甲基铵和18-冠－6为相转移催化剂时端羟基聚环氧氯丙烷在聚环氧乙烷和水为介质中的叠氮化反应，探讨了反应规律和反应机理，结果表明：以PECH为介质，十二烷基苄基三甲基氯化铵(TMDA-1)为相转移催化剂的反应体系，可在15h内使PECH叠氮化转化率达到97%以上，无主链断裂等副反应，是一条较为安全快速的制备叠氮粘合剂的方法。
