Disclosed is a method for producing a polybutadiene wherein 1,3-butadiene is subjected to a cis-1,4 polymerization by using a catalyst and then the resulting is subjected to a syndiotactic-1,2 polymerization in the same polymerization system. This method for producing a polybutadiene is characterized in that a halogen acid or a halogen acid salt is added after the polymerization. |
