摘要
以二甲基二烯丙基氯化铵(DMDAAC)和丙稀酰胺(AM)为原料，在 引发剂过硫酸铵(APS)的作用下，通过共聚合反应成了一种新的阳离子型聚合物。在n(DMDAA C)：n(AM)=2:1、c(APS)=2.0×10-2mol/L、t=60°Ｃ、T=3h的条件下，所得共聚物的 阳离子度(CD)为45%，相对分子质量为9.4×106。应用实验结果证明该聚合物具有良好的 絮凝作用，同时对共聚物的结构进行了表征。
A new cationic copolymer was synthesized by copolymeriz ation of dimethyldiacrolamine chloride (DMDAAC) and acrylamide(AM) in the presen ce of ammonium persulfate(APS) as initiator. When the molar ratio of DMDAAC and AM was 2∶1，concentration of APS was 2.0×10-2mol／L and the mixture reac ted at 60℃ for 3h, the yield of copolymer reached 96%. The result of analysis s howed that the cationic degree was 45% and the molecular weight was 9.4×106 . The experiment results show that it possesses better flocculation characteri stics.
