Abstract

Butadiene is polymerized in the presence of soluble catalysts prepared by contacting a compound of a metal of Group VIII with an alkyl metal compound and ageing the catalyst mixture in predetermined amounts in an inert hydrocarbon solvent at below 50 DEG C. for 5 minutes to 2 hours and mixing the aged catalyst with all the butadiene before the polymerization reaction is started. Specified catalyst components are diethyl aluminium chloride, cobaltous chloride-pyridine complexes, and cobalt diacetyl acetonate while benzene is the specified solvent.
