The process of this invention can be utilized to synthesize polymers having a high trans microstructure. The polymers which can be prepared utilizing the procedure of this invention include high trans-1,4-polybutadiene, styrene-isoprene-butadiene terpolymers with high trans-1,4-polybutadiene microstructures, high trans-isoprene-butadiene copolymers, and styrene-butadiene copolymers having high trans-1,4-polybutadiene microstructures. Such polymers can be utilized in tire tread rubber compounds which exhibit improved wear characteristics, tear resistance and low temperature performance characteristics. This invention more specifically reveals a process for synthesizing a high trans polymer which comprises adding (a) at least one organolithium initiator, (b) an organoaluminum compound, (c) a barium alkoxide, and (d) a lithium alkoxide to a polymerization medium which is comprised of an organic solvent and at least one conjugated diene monomer.
