Research on Grafting Maleic Anhydride onto Polyolefin with Melt Extrusion

The application of polyolefin(PE and PP) can be expanded by grafting maleic anhydride.The paper reviews the studies on mechanism of grafting maleic anhydride onto polyolefin(PE and PP),influential factors of the grafting ratio and methods of increasing the graft ratio in recent year,and gives some tentative ideas for future research.
