FIELD: chemistry. ^ SUBSTANCE: described is a method of producing butadiene rubber by feeding a mixture into a polymeriser, which contains butadiene or butadiene and isoprene and a hydrocarbon solvent, and a catalytic complex formed by reacting a rare-earth element, diene hydrocarbon, organoaluminium compound and an organohalogen compound, characterised by that, before feeding into the polymeriser, the catalytic complex is split into streams and at least two streams are fed at an angle less than 20 degrees to the stream of the mixture. ^ EFFECT: low consumption of the catalytic complex when producing butadiene rubber, obtaining butadiene rubber with the required quality index, including Mooney viscosity index. ^ 1 cl, 6 ex |
