    摘要: The present invention relates to preparing high 1,4-trans-polybutadiene by polymerizing 1,3-butadiene or a butadiene derivative in a non-polar solvent in the presence of a catalyst system comprising a novel bimetallic cobalt-aluminum adduct, which makes it possible to prevent gel formation, control the molecular weight of the trans-polybutadiene and increase the trans content of the trans-polybutadiene. The catalyst system comprising the novel cobalt-aluminum adduct has a high oxidation state and structural stability, and the reactivity of the catalyst is controlled using novel activation systems comprising various allyloxy aluminum compounds.
