Abstract

Grafting for maleic 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.
