| 摘 要： | 以铈离子和酰苯胺引发体系进行丙烯酰胺的聚合,研究了不同结构酰苯胺对聚合的影响。在H_2O-CH_3CN(3∶1)介质中聚合时,乙酰对甲苯胺对聚合的促进作用最为明显,聚合速度可提高一个数量级。测定了聚合反应的表观活化能和聚合动力学方程、由聚合物的原子发射光谱,UV光谱和端基测定,提出了聚合反应机理。

| Abstract: | Polymerization of acrylamide (AAM) initiated with eerie ion-acetanilide (AA) and its derivatives binary systems has been studied. It was found that cerie ion alone and eerie ion coupled with AA, acetyl p-toluidine (APT), acetyl p-chloroaniline (APCA), acetyl p-nitro-aniline (APNA), N-methyl acetanilide (NMAA), benzanilide (BA), N-methyl benzanilide (NMBA) and N-p-tolylbenzamide (NTBA) could initiate AAM to polymerize, The activity of amide on polymerization rate was investigated. The descending order of Rp was PAT >> AA APCA > BA > NMAA > APNA. The overall energy of polymerization Ea, the kinetic equation of polymerization and the end group of polymer obtained were determined respectively. |
