    摘要: A process for producing a polybutadiene, which comprises polymerizing 1,3-butadiene in an inert organic solvent with a catalyst comprising (A) a cobalt compound, (B) an organoaluminum compound consisting essentially of an aluminoxane and, if necessary, (C) a tertiary phosphine compound, (D) at least one compound selected from the group consisting of an ester compound, an alcohol compound, a phenolic compound, a sulfoxide compound, a nitrogen-containing heterocyclic compound, water and a tertiary amine compound and (E) at least one compound selected from the group consisting of carbon disulfide, a xanthogen compound and a thioisocyanide. By this process, there can be produced, as desired, a cis-1,4-polybutadiene, a 1,2-polybutadiene having a desired vinyl content, a crystalline 1,2-polybutadiene or a polybutadiene containing crystalline 1,2-polybutadiene segments.
