摘 要: 用双螺杆挤出机研究了马来酸酐(MAH)对聚丙烯(PP)的自由基熔融接枝。采用正交试验优化了熔融接枝条件,考察了引发剂过氧化二异丙苯DCP、单体MAH用量对马来酸酐接枝率的影响,并对其影响因素作了分析。研究表明改性以后的PP制成的PP膜性能更进一步提高。确定了较佳的原料(质量)配比为PP∶MAH∶DCP=100∶3∶0.4。 Grafting for maleie anhydride onto polypropylene was studied by means of a double - screw extruder. The condition of melt - grafting for maleic anhydride onto polypropylene was optimized by orthogonal experiment. The influences of the concentration of DCP, MAH on the ratio of grafting were investigated and analyzed. The experimental results show that the properties of the film made by modified PP were improved. The preferable proportion of reactant is PP : MAH : DCP = 100 : 3 : 0.4.
