Information

Copolymerization modification is a modification carried out in the synthesis stage of propylene monomer using catalysts such as metallocene. When the monomers are polymerized, the added olefin monomers are copolymerized with them to obtain random copolymers, block copolymers and alternating copolymers, etc. The mechanical properties, transparency and processing fluidity of homopolymerized PP are improved.

Graft modification is to introduce polar groups into its macromolecular chain to improve the blending, compatibility and adhesion of PP, and to overcome the shortcomings of difficult blending, incompatibility and adhesion. Under the action of the initiator, the grafting monomer undergoes grafting reaction during melting and kneading. The initiator decomposes when heated, melted and heated to generate active free radicals. When the active free radical encounters the unsaturated carboxylic acid monomer, the unsaturated carboxyl After the labile bond of the acid monomer is opened, it reacts with the PP active radical to form a graft radical, which is then terminated by molecular chain transfer reaction. The common graft modification methods of PP are: melting method, solution method, solid phase method, suspension method, etc. The hydrogen atoms in the graft-modified PP molecular chain are replaced to show strong polarity. These polar groups enhance the compatibility of PP, and greatly improve the heat resistance and mechanical properties.
