ABSTRACT OF THE DISCLOSURE The characteristics of barium t-alkoxide salts used with organlithium compounds as catalyst complexes in the solution polymerization of ethylenically unsaturated monomers to make polymers such as rubbers is improved by reducing or eliminating the nitrogen content of the barium salt and, further, by using a certain mixture of tertiary carbinols and water in forming the barium salt. In certain instances water may be eliminated.
