通过含有伯氨基和仲氨基的氨基遥爪聚合物与环氧氯丙烷的反应，合成了主链中具有氮杂环丁烷鎓基团的功能聚合物。在反应过程中，仲氨基转化为氮杂环丁烷鎓基团，伯氨基转化为氨基-氯代醇、氨基-环氧化物和氮杂环丁烷鎓基团。通过调节反应条件来控制聚合物中所需官能团的形成。为了了解生成所需官能团的反应条件的影响，伯胺和仲胺与环氧氯丙烷的模型反应进行了详细的研究，包括原料的摩尔比的影响，溶剂的效果，pH值的效果，和反应动力学。
Functional polymers with azetidinium groups in the backbone are synthesized via the reaction of aminotelechelic polymers, containing primary and secondary amino groups, with epichlorohydrin. During the reaction, the secondary amino groups are transformed into azetidinium groups and the primary amino groups are transformed into amino-chlorohydrin, amino-epoxide, and azetidinium groups. The formation of desired functional groups in the polymer is controlled by tuning the reaction conditions. To understand the influence of reaction conditions generating the desired functional groups, model reactions of primary and secondary amines with epichlorohydrin are studied in detail, including the influence of the mole ratio of the starting materials, effect of solvent, effect of pH, and reaction kinetics.
