It was studied different catalytic systems type Ziegler synthesized from an organic salt of a transitional metal and an organo-metallic compound type Lewis base. It is presented a synthesis method for cobalt (or nickel) octoate and cobalt (or nickel) 2-ethyl-hexanoate. The influence of catalyst concentration and molar ratio between the two components onto the hydrogenation conversion is also studied. The soluble catalysts synthesized were employed for the hydrogenation of unsaturated polymers resulting conversions up to 95%.
