Modificated Methods of Maleic Anhydride onto Polypropylene and Its Application

Maleic anhydride （MAH） is the usual polar monomer in the modification of polypropylene. The anhydride group shows high activity in the continuous reaction, and the result turns out to be good thermostability, the products are widely used in alloy, plastic industry. With a variety of other technology, modificated methods for grafting maleic anhydride onto polypropylene have been developed rapidly, maily involving solution grafting, melt grafting, solid phase grafting and radiation grafting. In this paper, the relative merits and the advances in research of each method are reviewed, and the applications in different fields are introduced.
