Using the dimer 4-methyl-2-pentene of propylene as the monomer, stereoisotactic polymers can be obtained through directional polymerization. The preparation process of the monomer 4-methyl-2-pentene is to remove trace impurities and strictly control the propylene of water. Under the conditions of 0.101-10.13MPa (1-100atm) and 40-205 ℃, under the action of Ziegler catalyst, the dimerization reaction is carried out, and the reaction product undergoes efficient, monomers with a concentration of 97.7% can be obtained.
