【摘要】 乙醇作溶剂 ,考察了引发剂浓度、单体浓度、聚合时间、聚合温度、引发剂类型对N -对甲苯基马来酰亚胺与苯乙烯的共聚活性的影响 ,得到最佳聚合条件。通过GPC分析 ,测得共聚物分子量。通过红外、核磁共振的联合测定 ,证明N -对甲苯基马来酰亚胺与苯乙烯聚合时能有效地打开双键 ,聚合按交替方式进行。更多还原

【Abstract】 The activity of copolymerization system of N-p-methylphenyl maleimide with styrene was systematically studied. Ethanol was used as solvent, and the optimum polymerization condition was found of initiator concentration , monomor concentration, polymerization time , polymerization temperature and initiator type. By GPC analysis, the molecular weight of the copolymer was testified. The results of Infra-red and Nuclear Magnetic Resonant analysis showed that the double bond of N-p-methylphenyl maleimide was split when it was polymerized with styrene, and the copolymerization was alternately carried out.更多还原
