摘要：

On the basis of the results obtained with various substituted dialkenes, including deuterated monomers, an interpretation is presented of the mechanism of formation of the following polymers: 1,2 iso- and syndiotactic polybutadiene; cis-1,4 iso- and syndiotactic polypentadiene; 1,2 syndiotactic poly(5-methyl-1,3-pentadiene); trans-1,4 threo diisotactic poly(2,4-hexadiene). Evidence is given that the ligands bonded to the transition metal of the catalyst are important in determining the orientation of the incoming monomer.
