摘　　要：采用二甲胺与三甲胺对聚环氧氯丙烷进行阳离子改性,合成了一种新型铵盐阳离子产品—聚环氧氯丙烷铵(PECHA),采用红外光谱、核磁氢谱及核磁共振碳谱对产品的结构进行表征。同时评价了其在絮凝性能和粘土稳定性能,实验表明:PECHA浓度为4.0mg/L时钠蒙脱土污水浊度除去率高达97%;而PECHA浓度为2.5mg/L时,其防膨性能可高达80%;且摩尔比1:1的PECHA与氯化锌复配絮凝剂在处理含油污水中表现出良好的性能。The cationic poly （epichlorohydrin） of ammonium salts was synthesized by dimethylamine, trimethylamine and poly（epichlorohydrin）. And the chemical constitution was discussed by methods of IR, ^1H-NMR and ^13C-NMR. The result of performance of flocculation and prevention swelling were that the removing of turbidity can reach 97 %, when concentration of PECHA was 4.0 mg/L, and the swelling rate of clay was less than 20 % at 2.5 mg/L, and there was a good performance in oil sewage, when the compound of PECHA and ZnCl2 was 1：1.
