Poly-4-methyl-1-pentene (PMP) has high technical barriers and my country has not yet achieved domestic production.

poly-4-methyl-1-pentene (pmp) is a new type of thermoplastic resin. it is mainly produced by the dimerization of propylene to obtain the monomer 4-methyl-1-pentene, which is then polymerized using a ziegler-natta catalyst or a metallocene catalyst. and get. pmp can be formed by injection molding, blow molding, extrusion and other methods. it has the advantages of…
