Process for controlling degree of branch of high 1,4-cis polybutadiene
Disclosed is a process of controlling the degree of branch of high 1,4-cis polybutadiene without any alternation in the 1,4-cis content and the polymerization yield, in which a dialkylzinc compound represented by the following formula I is added in a controlled amount as an agent for controlling the degree of branch of high 1,4-cis polybutadiene, thus guaranteeing the optimum processability and physical properties of polymer according to the use purpose.R1&#8212;Zn&#8212;R2&#8195;&#8195;Formula I wherein R1 and R2 are same or different and include an alkyl group containing 1 to 5 carbon atoms.
