FIELD: catalytic chemistry. SUBSTANCE: proposed catalyst contains organoaluminic compound as a base. Said compound has formula RnAlCl3-n where R is alkyl, n=1 or 2 and it also contains 3.52-4.27 mass% of O,O-bisubstituted dithioderivative of transition metal having formula (image) where Me is cobalt or nickel, R1 and R2 are C1-C8-alkyl or C5-C8-cycloalkyl. Mentioned above catalyst provides 98% conversion of polybutadiene and productivity 72 kg/g cobalt per 1 hour or 100% conversion and productivity 110 kg/g nickel per 1 hour. EFFECT: increases activity of catalyst. 2 tbl
