  The invention relates to the industry of synthetic rubbers used in the manufacture of tires, industrial rubber goods, in the electrical engineering and other fields. In particular, the present invention relates to a method for producing modified polydienes in an organic solvent on a catalytic system comprising a lanthanide compound, an organoaluminum compound, and a halogen-containing component, followed by terminal modification of the produced "pseudo-living" polymer with at least one compound selected from the group of heterocyclic nitrogen-containing compounds. The present invention also relates to modified polydienes produced by this method. In addition, the invention relates to rubber mixtures based on the produced polydienes. The resulting modified polydiene is characterized by a high degree of modification (not less than 90%), a high content of 1,4-cis-units, by a narrow molecular weight distribution, and an improved processability at the step of rubber mixing; the rubbers produced from the modified polydienes are characterized by an increased wear resistance and improved physical and chemical properties, as well as by improved elastic hysteresis properties (rolling resistance, wet-tire traction).
