摘　　要：合成了可聚合芳香叔胺 -3-甲基丙烯酰胺基 -9-乙基咔唑 ,并与过硫酸钾组成氧化还原引发体系引发丙烯酰胺水溶液聚合 ,测定了聚合反应动力学 ,得到了超高分子量的聚丙烯酰胺。The polymerization of AM initiated by 3-methacrylamido-9-ethylcarbanzole(MAAECz) and potassium persulfate were studied kinetically. The rate equation and overall activation energy for the AM polymerization initiated by the above initiation system were obtained. The UV analysis for PAM initiated by the above initiation system confirmed that the polymerizable MAAECz not only joined the redox initiation but also incorporated into the AM polymer chains. The ultra high molecular weight PAM was obtained by using this initiation system.
