Epoxides, episulphides and ethylene imines also polymerize via similar cyclic onium ion mechanisms . 环氧化合物，环硫化合物和乙烯亚胺也可以按类似于环氧离子的机理进行聚合。
The oh functionality of the polyether may be controlled by using modifiers such as glycidol, ethylene glycol, water or trimethylol propane . 用缩水甘油、乙二醇，水或三羟甲基丙烷等改良剂，可控制聚醚的羟基官能团。
