Summary:FIELD: polymerization catalysts. SUBSTANCE: in hydrocarbon solvent, VIII group metal compound (product of interaction of hydrocarbon-soluble cobalt or nickel salt with alkylaluminum halide or aluminum halide) is brought into reaction with alkylaluminum chloride and conjugated diene at molar ratio VIII group metal/aluminum/diene 1:(5-20):(5-50). EFFECT: more than 20 times reduced required amount of alkylaluminum chloride and significantly prolonged catalyst storage time. 4 ex
