    摘要: A process for producing polymers of a conjugated diene, copolymers of a conjugated diene and another conjugated diene, or copolymers of conjugated diene and a vinyl aromatic hydrocarbon, which comprises polymerizing the corresponding monomers in the presence of a complex initiator consisting of components (a) and (b) described below, or (a) and (b) together with one or more components selected from components (c) and (d); (a) An organic compound of barium, strontium or calcium; (b) An organolithium-beryllium compound or an organolithiummagnesium compound; (c) An organolithium compound, an organoberyllium compound or an organomagnesium compound; and (d) An organoaluminum compound or an organozinc compound. The polymers of a conjugated diene containing relatively high trans-1,4 linkage, or the copolymers of a conjugated diene and a vinyl aromatic compound highly randomized and having high bound styrene and high trans-1,4 linkage can be produced at good yields.
