In view of the poor impact resistance of polypropylene at low temperature, poor weather resistance, poor surface decoration, and the gap between the functional and actual needs in electricity, magnetism, light, heat, combustion, etc., polypropylene is modified to become a At present, the development of plastic processing is the most active and the field with the most fruitful results.
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. The complex formed by copolymerization is a transition state with a limited irregular shape as a single active center, which can precisely control the relative molecular mass and its distribution, the content of comonomers, the distribution on the main chain and the crystal structure of the polymer.
