| 摘 要： | 研究了N,N-二甲基对甲苯胺(DMT)为引发剂时丙烯酰胺(AM)的光聚合。聚合速率与AM、DMT浓度的关系为: R_p∞DMT]~(0.35)AM]~(1.34)(水为溶剂) R_p∞DMT]~(0.33)AM]~(1.32)(二甲亚砜为溶剂)二甲亚砜为溶剂时,光聚合表观活化能为4.62千卡/克分子。 从光照下DMT与AM形成激发态电荷转移复合物的机制初步讨论了引发机理。

| Abstract: | The photopolymerization of aerylamide (AM) initiated with N, N-dimethyltoluidine (DMT) has been studied. The kinetic results show the rate of polymerization in the form ofRp∝DMT]0.35AM]1.34(in H2O) Rp∝DMT]0.33AM]1.32(in DMSO)and the apparent energy of activation of photopolymerization Ea to be 4.62 Kcal/mol. Some tentativemechanism of this photopolymerization has been proposed. |
