Polypropylene (PP) is a general polymer material with excellent performance and low price. However

the use of PP has been restricted by its poor dyeability

hydrophilicity

cohesiveness

and poor compatibility with other materials because of the nonpolarity of PP. Introduction of polar functional group to molecular chain of polypropylene (PP) by the method of solid phase grafting copolymerization would not only keep the original excellent properties of PP

but also have the advantages of low temperature

low pressure

low cost

high grafting degree and no need of solvent recovery

etc. In this paper

the reaction mechanism of solid-phase grafting was briefly introduced

and the latest advances in solid phase grafting copolymerization of polypropylene from the aspect of grafting monomers were reviewed. The effect of the reaction technology on grafting degree

grafting efficiency and properties of grafting copolymer was then discussed.
