| 摘 要： | <正> N-乙烯基咔唑(NVC)具有大的共轭结构和中间有一个杂原子氮,而容易与其它试剂反应,形成自由基、阳离子和电荷转移络合物,故是一种活性较高的单体,1970年有人发现NVC与N-C_4H_9NCl_2一起可以引发甲基丙烯酸甲酯(MMA)聚合,此外,文献报道了电子给体如胺与CCl_4体系在二甲亚砜(DMSO)中引发MMA聚合,本文研究了NVC与几种卤代烃所组成的双组分体系对MMA的引发聚合反应;该体系的引发活性和组成与分子量及分子量分布的关系;并探讨了反应机理。

| Abstract: | The polymerization of methyl methacrylate with N-vinylcarbazole and halogenated compounds as initiators have been investigated. The initial activity of the new initiator systems, the influence of irradiation, temperatures and solvents on polymerization were examined. The induction periods increase with increase of DPPH concentration. The molecular weight and dispersivity of poly (methyl methacrylate) obtained were measured. |
