【Abstract】 Much attention has been attracted to the modification of polyolefins re cently. Modification under melt condition was a suitable way to improve the pr operties of PP and PE, both of which belong to the thermal-plastic materials. I n this paper, the grafting monomers, s uch as the acrylic acid and maleic anhydride and their derivates were mainly rev iewed. The ways of increasing the graft yields and compatibilities, characte rization of the polyolefin were also described.更多还原
