摘　　要：通过丙烯酰（ＡＭ）的Ｍａｎｎｉｃｈ反应制备的含叔胺基改性丙烯酰胺胺盐酸盐（ＣＡＭ）同二甲基二烯丙基氯化铵（ＤＭ）共聚，得到了共聚物ＣＡＭ－ｃｏ－ＤＭ，其絮凝和防膨性能优于相同阳离子度的共聚物ＡＭ－ｃｏ－ＤＭ。A modified acrylamide,CAM.chemically N-dimethylaminomethylacrylamide hydrochloride, is prepared by Mannich's reaction of acrylamide.Two copolymers CAM-co-DM and AM-co-DM of similar degrees of cationzation(17.30% and 17. 24%) are obtained in initiated copolymerization processes of CAM and dimethyldiallylammonium chloride (DM) and AM and of DM. The flocculationg and anticlayswelling capacties of CAM-co-DM are higher than that of AM-co-DM.as shown in laboratory comparative evaluation tests.
