N-苯基马来酰亚胺与苯乙烯共聚活性的研究

Study on the activity of copolymerization of N-phenyl maleimides with styrene

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－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、TGA分析，测得共聚物分子量及热稳定性。通过红外、核磁共振的联合测定，证明N－苯基马来酰亚胺与苯乙烯聚合时能有效地打开双链，并且聚合是按交替方式进行的。

The activity of copolymerization system of N-phenyl maleimide with styrene was systematically stud-ied. Ethanol as solvent, the optimum polymerization condition of initiator concentration, monomor concentra-tion, polymerization time, polymerization temperature and initiator type were obtained . By GPC and TGA analysis,the molecular weight and thermal stability of the copolymer were testified. The result of Infra-red and Nuclear Magnetic Resonant analysis illustrated that the double bond of N-phenyl maleimide was splitted when polymerizing with styrene,and the copolymerization was carried out in the way of alternation.
