摘要
采用熔融法制备乙烯-1-辛烯共聚物(POE)接枝甲基丙烯酸环氧丙酯(GMA),利用红外光谱对其结构进行表征。考察了GMA和过氧化二异丙苯(DCP)用量以及反应温度和反应时间对接枝率的影响,实验结果表明,GMA用量增加,接枝率逐渐增大,熔体流动速率逐渐下降;随着引发剂用量的增加,接枝率也随之增加;同时随着反应温度和反应时间的变化,接枝率随之变化。
Glycidyl methacrylate(GMA) grafting ethylene- 1 -octene (POE) was prepared by melting process and the structure was studied by IR. The influences of the monomer content, initiator content, reaction temperature and time on the grafting ratio were studied. The results showed that the grafting ratio increased with the increasing content of initiator and GMA.
