Abstract
Catalytic polymerization process of butadiene to obtain an elastomer butadiene polymer in which at least 50% of the butadiene polymer units are present in the cis-1,4 form, characterized in that the butadiene is contacted with a catalyst formed essentially by titanium tetraiodide and a di-lithium polymethylene compound in which the molar ratio of lithium coupled to the carbon to titanium tetraiodide in said catalyst is not greater than about 3: 1.
