Abstract RU 2640800 C2

FIELD: chemistry.

SUBSTANCE: method comprises (i) polymerization of monomers with the formation of the reactive polymer, wherein the monomer includes a conjugated diene monomer, at a specified stage of polymerization using a coordination catalyst, and the said reactive polymer has a reactive end of the chain, and (ii) carrying out reactions of this reactive polymer with glycidyl ether. Also, a bound polymer and a tire component derived from a bound polymer are described.

EFFECT: improved resistance of the bound polymer to cold flow.
