Abstract

The invention relates to the production of synthetic polymers used in the manufacture of tires and rubber technical products, in electrical industry and other fields. In particular, the present invention relates to a method for producing a branched polydiene by polymerization of a conjugated diene, the method comprising the following steps: preparing a catalyst complex consisting of a lanthanide compound, an organoaluminum compound, a conjugated diene and a halogen-containing component; polymerizing the conjugated diene in the presence of said catalyst complex; performing post-polymerization modification with at least one branching agent selected from halogen containing compounds, phosphorus-nitrogen compounds or mixtures thereof; termination, introducing a plasticizer into the polymer, wherein the plasticizer is a low molecular weight polymer having a molecular weight between 1500 and 50,000 g/mol, degassing, and drying the polymer. In yet another aspect, the present invention relates to a method for producing rubber compositions based on the above branched polydiene. The technical result of the present invention is the preparation of a branched polydiene characterized by a Mooney viscosity from about 40 to about 49 Mooney Units (MU) and a branching index, as characterized by a mechanical loss angle tangent tgd (1200%), from about 4.7 to about 5.3. The polydiene produced according to the invention has an improved processability, an improved distribution of the filler in the polymer matrix, and rubber compositions based on it are characterized by improved elastic-hysteresis properties (namely, Mooney viscosity ML(1+4), MU, a Payne effect (G'1%-G'50%), kPa, Tand 60C at 10% deformation.
