聚环氧氯丙烷阳离子改性与应用研究

Synthesis and Application of Cationic Poly （epichlorohydrin）

采用聚环氧氯丙烷（PECH）与乙二胺和三甲胺合成一种新型聚胺盐型高分子——聚环氧氯丙烷胺（PECHA）．利用IR、1H—NMR对聚合物的结构进行了表征，同时对聚合物的絮凝性能和粘土稳定性能进行了探讨．结果表明，当CPECHA=4．0mg／L时，钠蒙脱土污水浊度除去率高达98％，CPECHA=2．0mg／L时，粘土稳定性能高达86．96％．

The cationic poly（epiehlorohydrin） of ammonium salts was synthesized by ethylenediamine, trimethyl- amine and poly（epichlorohydrin）. And the chemical constitution is discussed by methods of IR, 1H -NMR and 13C - NMR. The result of performance of floeculation and anti-swelling shows that the removing of turbidity can reach 98% , when concentration of PECHA is 4.0mg/L, and rate of anti-swelling can reach 86.96% at 2.0mg/L.
