摘要： A process for preparing polybutadiene having a 1,2-configuration content of 5-40% and a cis-1,4-configuration content of 60% or more, which comprises polymerizing 1,3-butadiene in the presence of a catalyst consisting of:(A) a cobalt compound,(B) at least one member selected from the group consisting of:(i) a trialkylaluminum,(ii) a reaction product of a trialkylaluminum and an alcohol or water,(iii) a mixture of a trialkylaluminum and a dialkylaluminum halide,(iv) a dialkylaluminum hydride, and(v) an organolithium compound, and(C) at least one compound selected from the group consisting of phenyl isothiocyanate and carbon disulfide, in a hydrocarbon or halogenated hydrocarbon solution of a high cis-1,4-polybutadiene obtained by polymerizing 1,3-butadiene with a catalyst consisting of:(D) at least one compound selected from the group consisting of the organocarboxylates of nickel and organic complex compounds of nickel,(E) at least one compound selected from the group consisting of boron trifluoride, boron trifluoride complex compounds and hydrogen fluoride, and(F) at least one compound selected from the group consisting of the organometallic compounds of the alkali metals of the Group II or III metals of the Periodic Table. The polybutadiene produced by this process has an improved tear strength and improved flexural fatigue properties.
