摘  要:Ce^(4+)-Ce^(3+)循环体系引发淀粉与丙烯酰胺接枝共聚合反应动力学研究张连生,王玉芹,杨巍(黑龙江大学化学系,哈尔滨,150080)(黑龙江商学院商管系,哈尔滨,150076)关键词Ce^(4+)-Ce^(3+)循环引发、Ce^(4+)复合引发?..The cyclic initiating system of Ce ̄4+ - Ce ̄3+ - Ce ̄4+, in which the product of reduced ion Ce ̄3+ forming from Ce ̄4+ after initation being oxidized again to the original oxidizing ion Ce ̄4+ is examined. The characters of process of the graft copolymerisation using the cyclic initiating system is compared with the ones using ceric and persulphate individually. When using the cyclic systerm as initator, it was more effective to graft polymerise acylamide onto starch and a rather high proportion of graft copolymer was made as opposed to using persulphate individually.
