摘要: 考察了单体配比、温度、引发剂浓度诸因素对氯乙烯(VC)/N-苯基马来酰亚胺(PMI)悬浮共聚速率的影响.VC/PMI共聚有显著的交叉终止,致使共聚速率降低,测得交叉终止速率常数的函数=5.77,PMI均聚综合速率常数的倒数值δ2=53.65,共聚表观活化能Ea=127.9kJ/mol,增长活化能Ep=63.7kJ/mol,聚合速率对引发剂浓度的反应级数为0.786.并对VC/N-环己基马来酰亚胺(CHMI)和VC/PMI两个体系进行了比较.

Abstract: The effects of monomer ratio, temperature and initiator concentration on the copolymerization rate of vinyl chloride(VC)/N-phenyl maleimide(PMI) were studied. The cross termination Φ and the reciprocal of the comprehensive rate δ2 were measured to be 5.77 and 53.65, respectively. The results showed that the copolymer composition of VC/PMI will largely change with the conversion. The activation energy of VC/PMI copolymerization and the propagation reaction are 127.9 kJ/mol and 63.7 kJ/mol, respectively. The order of initiator is 0.786. The reaction rates between VC/PMI and VC/N-cyclohexyl maleimide (CHMI) are compared, and the later is more rapid than the former.

Key words: Vinyl chloride, N-phenyl maleimide, Suspension copolymerization
