Abstract:
The present invention relates to a process of preparing 1,4-trans polybutadiene grafted with an aromatic organosulfur compound, the process comprising (a) preparing 1,4-trans polybutadiene by polymerizing 1,3-butadiene or butadiene derivatives in a nonpolar solvent in the presence of a particular catalyst, and (b) preparing the 1,4-trans polybutadiene grafted with an aromatic organosulfur compound by reacting the trans polybutadiene with an aromatic organosulfur compound. The organosulfur molecule in the molecular chain minimizes ultra high molecular weight fraction and narrows the molecular weight distribution, thereby enabling this polymer to show improved processability and tensile properties.
