PP polypropylene resin molecules have a non-polar crystalline linear structure, with low surface activity and non-polarity. It has the disadvantages of poor surface printability; poor coating adhesion; difficult to blend with polar polymers; and difficult to be compatible with polar reinforcing fibers and fillers. The graft modification is to introduce polar groups into the macromolecular chain to realize the blending, compatibility and cohesiveness of PP, so as to overcome the shortcomings of difficult blending, difficult compatibility and difficult bonding. Under the action of the initiator, the grafting monomer undergoes grafting reaction during melting and kneading. The initiator decomposes to produce active free radicals when heated, melted and heated. When the active free radicals meet the unsaturated carboxylic acid monomer, the unsaturated carboxylic acid After the unbonded monomer is opened, it reacts with the PP active radical to form the grafting radical, which is then terminated by a molecular chain transfer reaction. The common graft modification of PP are: melting method, solution method, solid phase method, suspension method and so on. The hydrogen atoms in the PP molecular chain after graft modification are replaced to show strong polarity. These polar groups enhance the compatibility of PP, and the heat resistance and mechanical properties are great.
