Abstract

The present invention relates to the synthetic rubber industry, in particular to the production of polymers for the production of tires and other rubber products. In particular, the present invention relates to a method for the preparation of a modified polydiene, the method comprising the following steps of i) preparing a catalyst complex including (A) a lanthanide compound, (B) a conjugated diene, (C) an organoaluminum compound, and (D) a halogen-containing component; ii) polymerizing a conjugated diene in an organic solvent medium in the presence of the catalyst complex obtained in step i); iii) on reaching at least 96% conversion of the monomer, introducing a modifying agent into the polymer, wherein the modifying agent is a low molecular weight polybutadiene containing terminal alkoxy silane groups; iv) terminating the polymerizate obtained in step iii), introducing an antioxidant and recovering the polymer.
