摘要
本文以二过碘酸合铜(Ⅲ)络离子(简称Cu(Ⅲ))为引发剂,聚丙烯酰胺为还原剂组成氧化还原引发体系,在聚丙烯酰胺上引发甲基丙烯酸甲酯接枝共聚合反应,获得了具有一定接枝效率和接枝百分比的接枝共聚物。测定了各种反应条件对接枝参数的影响,并对引发机理进行了探讨。
The graft copolymerization of methylmethacrylate ( MMA) onto polyacrylamide (PAAM) was studied by using potassium diperiodatocuprate (III) as the initiator. It was found that potassium diperiodatocuprate-PAAM complex is an efficient redox initiator for the graft copolymerization. The effects of the temperature and concentrations of initiator and MMA on the reaction were investigated.An initiation mechamism was proposed.
