Aromatic organosulfur functionalized 1,4-cis polybutadiene
The present invention relates to a preparation method of aromatic organosulfur functionalized 1,4-cis polybutadiene comprising: polymerizing 1,3-butadiene or butadiene derivative in the presence of a specific catalyst in a nonpolar solvent to prepare 1,4-cis polybutadiene; and reacting the resultant polybutadiene with an aromatic organosulfur compound. Such prepared aromatic organosulfur functionalized 1,4-cis polybutadiene is without ultrahigh molecular weight region and, thus, has narrow molecular weight distribution.
