Abstract:
A method for producing a polybutadiene, which comprises subjecting 1,3-butadiene to cis-1,4 polymerization, and subsequently subjecting a resultant in the resulting polymerization system to syndiotactic-1,2 polymerization, the method being characterized in that there is added, after the polymerization, a halogen acid or halogen acid salt.
