FIELD: chemistry.
SUBSTANCE: invention relates to methods of producing polydienes with high content of cis-polybutadiene links. Disclosed is method of producing polydiene involving following stages in said order: i) polymerisation of one or several diene monomers in presence of catalyst composition for producing reaction mixture; II) adding to reaction mixture of one or several alkoxylane compounds, iii) addition S2Cl2, SCl2, SOCl2, S2Br2, SOBr2 or their mixture in reaction mixture; and iv) optionally adding to the reaction mixture proton containing agent to deactivate catalyst. Also disclosed are polymers obtained according to method, and products that contain polymer.
EFFECT: technical result is disclosed method enables to obtain polydienes with improved processing properties suitable for production of tires with improved operational characteristics, such as rolling resistance and resistance to wear.
