摘　　要：合成了阳离子单体N,N-二甲基二烯丙基氯化铵(DMDAAC)及其与丙烯酰胺(AAM)的共聚物。对单体及共聚物的合成方法进行了概述,并探讨了此阳离子型共聚物的稀溶液性质,包括导电性质和粘性行为。The cationic monomer dimethyldiallylammonium chloride (DMDAAC) was synthesized by two steps, namely dimethylamine was treated with allyl chloride under alkali condition, after this produced dimethylallyamine was separated and then quaternized with allyl chloride to obtain DMDAAC. The copolymer of DMDAAC and acrylamide (AAM) was prepared in aqueous solution with redox initiator. The solution properties of cationic polymer were studied, including electrical conductivity and viscosity behavior. The dependence of specific and equivalent conductivity of the copolymer on concentration, temperature and its cation ratios were investigated, respectively. And the relationships between reduced viscosity of copolymer and its concentration in pure water, in various aqueous solutions of different salts and in various of CH3OH/H2O mixture solvents were discussed in details.
