Abstract

Butadiene polymers of high molecular weight and cis 1-4 structure are prepared by polymerizing 1-3-butadiene in the presence of a soluble catalyst obtained from alkyl metal compounds and compounds or complexes of metals of Group VIII wherein the polymerization is effected in the presence of an alpha-mono olefin or non-conjugated diolefin. Specified catalyst components are cobaltous chloride, a cobalt chloride-pyridine complex, and diethyl aluminium chloride while ethylene, propylene, butene-1, allene, 1-2-butadiene and ethyl allene are specified additives. These additives may be added together with the butadiene or before adding the catalyst or after addition of catalyst or after polymerization has started. Benzene is the preferred solvent and the process may take place continuously.
