摘　　要：通过固相接枝的方法,将甲基丙烯酸缩水甘油酯(GMA)接枝到均聚聚丙烯(iPP)上,考察了反应温度、反应时间对接枝反应效率、产物凝胶含量及熔体质量流动速率(MFR)的影响。结果表明:当投料比为m(PP):m(GMA):m(BPO)=100:5:0.125时,反应温度为100℃,反应时间15min,接枝效率即可达到75%以上。反应时间的缩短对于实现GMA接枝改性聚丙烯的产业化有价值。Glycidyl methacrylate(GMA)was grafted onto homo-polypropylene(iPP)by solid-phase grafting.The effects of reaction temperature and reaction time on the grafting reaction were investigated.When the feeding ratio is m(PP):m(GMA):m(BPO)=100:5:0.125,reaction temperature is 100℃,reaction time is 15min,the grafting efficiency can reach more than 75%.The shortening of the reaction time is benefit to the technology’s commercialization.
