    • PURPOSE: A group IIa metal containing catalyst system is provided to synthesize rubbery polymers to be utilized as tire tread rubbers that exhibit improved wear and tear characteristics. CONSTITUTION: The catalyst system is characterized by being comprised of (a) an organolithium compound, (b) a group IIa metal salt selected from the group consisting of group IIa metal salts of amino alkyl glycols and group IIa metal salts of glycol alkylene ethers, and (c) an organometallic compound selected from the group consisting of organoaluminum compounds containing less than 13 carbon atoms and organomagnesium compounds. The process for synthesizing rubbery polymers having a high trans microstructure is characterized by polymerizing a conjugated diolefin monomer in an organic solvent at a temperature that is within the range of 40 deg.C to 120 deg.C in the presence of a catalyst system that is comprised of (a) an organolithium compound, (b) a group IIa metal salt selected from the group consisting of group IIa metal salts of amino glycols and group IIa metal salts of glycol ethers, and (c) an organometallic compound selected from the group consisting of organoaluminum compounds and organomagnesium compounds.
