FIELD : technological processes. SUBSTANCE : invention relates to methods of producing a catalyst for polymerisation of butadiene and can be used in production of rubber of general purpose in the industry of synthetic rubber. Disclosed is a method of producing a catalyst for polymerisation of butadiene by reacting rare earth elements (REE) chlorides with a monohydric alcohol and a solvent, followed by mixing with a conjugated diene and an organoaluminium compound, method consists in that monoatomic alcohol is 2-ethylhexyl alcohol in molar ratio of rare-earth elements : 2-ethylhexyl alcohol = 1 : 1.8–3.0. EFFECT : disclosed synthesis method enables to obtain a catalyst with high activity (yield of polybutadiene – 93–97 %) while reducing synthesis time thereof and obtaining a polymer with optimum Mooney viscosity. 1 cl, 6 ex
