以可聚合离子液体表面活性剂氯化-1-正辛基-3-(4-丙烯酸丁酯基)咪唑(PMOIH8)、丙烯酰胺(AM)以及2-丙烯酰胺基-2-甲基丙磺酸钠(NaAMPS)为单体,采用单电子转移活性自由基聚合(SET-LRP)法进行了三元共聚合反应,合成了一种两性离子聚丙烯酰胺P(AM/PMOIH/NaAMPS).分析结果表明所得产物为目标产物.考察了CuCl2、引发剂、温度等因素对聚合的影响.结果表明,体系中未加CuCl2时,聚合反应速率变慢,速率常数(kappp)由0.0144 min-1降低至0.0117min-1,-Mw/Mn由1.30增大为1.38,引发效率(Idf)降低至92.76%;增加引发剂用量,kappp增加至0.0153 min-1,-Mw/-Mn减小为1.26,Icff增加至95.18%;降低温度,kappp降低至0.0102min-1,-Mw/-Mn减小为1.28,I.ff降低至92.97%.
