摘要：
A process for producing a conjugated diene polymer, which comprises polymerizing (a) a conjugated diene, (b) two or more conjugated dienes or (c) at least one conjugated diene with a monovinyl aromatic compound, at a temperature of from about 30 to about 100.degree. C in an inert hydrocarbon solvent in the presence of a catalyst composition comprising (i) an alkenyl sodium containing 3 to 8 carbon atoms in the alkenyl moiety and (ii) a sodium alkoxide of a dimethylalkyl carbinol containing 1 to 5 carbon atoms in the alkyl moiety.
