摘　　要：以丙烯酰胺(AM)和甲基丙烯酰氧乙基三甲基氯化铵(DMC)为单体,在氧化还原引发体系中,通过水溶液聚合法合成了阳离子型聚丙烯酰胺聚合物(CPAM)。讨论了聚合单体质量分数、反应时间、反应体系温度、pH等因素对聚合反应的影响。结果表明,合成高分子量和阳离子度CPAM的最佳聚合条件为:聚合单体浓度为15%,引发剂0.06%,反应体系温度85℃,pH值为6左右,反应时间3 h。Cationic polyacrylamide [P（AM-DMC）] was synthesized by aqueous copolymerization of acrylamide（AM） and 2-trimethylammonium ethyl methacrylate chloride（DMC） using composite initiator system.The influences of monomer concentration,reaction time,initial temperature,pH value on copolymerization were discussed.The results showed that the optimal synthetic parameters for producing higher molecular weight and cationic degree of CPAM were as follows：monomer concentration was 15%,the amount of oligomer was 0.06%,the initial temperature was 85 ℃,pH value was 6 and reaction time was 3 h.
