    Abstract: The present invention relates to high trans 1,4-polybutadiene. In order to produce the 1,4-polybutadiene that has a high transformation rate, 1,3-butadiene or a butadiene derivative is polymerized by a catalyst system, in a type of a nonpolar solvent and a novel bimetallic cobalt-aluminum adduct, to prevent gelation and to adjust molecular weight. According to the present invention, the novel catalyst in a type of a cobalt-aluminum adduct is polymerized to increase stability of oxidation and structure and a novel activation system is developed using various alkyl allyloxy aluminum to regulate reactivity of the catalyst.
