Product Description

PP (Polypropylene) resin molecules have a non-polar crystalline linear structure, low surface activity, and no polarity. There is poor surface printability; Poor coating adhesion; Difficult to blend with polar polymers; The disadvantage of being incompatible with polar reinforcing fibers and fillers. Graft modification is the introduction of polar groups onto its macromolecular chains to improve the blending, compatibility, and adhesion of PP, overcoming the drawbacks of difficult blending, compatibility, and adhesion. Under the action of the initiator, the grafting monomer undergoes grafting reaction during melt mixing. The initiator decomposes and produces active free radicals when heated during melting. When the active free radicals encounter unsaturated carboxylic acid monomers, they promote the opening of unstable bonds between unsaturated carboxylic acid monomers and react with PP active free radicals to form grafting free radicals, which are then terminated through molecular chain transfer reaction. The common grafting modification methods for PP include melting method, solution method, solid-phase method, suspension method, etc. The hydrogen atoms in the grafted modified PP molecular chain are replaced and exhibit strong polarity. These polar groups enhance the compatibility of PP, greatly improving its heat resistance and mechanical properties Polypropylene PC Or ABS Polyformaldehyde Ea039df786eea3c8d416e442f0c0572 Jpg
