FIELD: chemistry.
SUBSTANCE: invention relates to polymers, functionalised with polycyanocompounds, and to a method of their obtaining and can be applied in tyres - side-piece and tread. The functionalised polymer is obtained in stages: (i) polymerisation of a conjugated diene monomer and optionally a monomer copolymerised with it with the formation of a reactionable polymer; and (ii) interaction of the reactionable polymer with polycyanocompound, with a coordination catalyst or an initiator of anionic polymerisation being applied at the polymerisation stage.
EFFECT: invention makes it possible to reduce hysteresis and cold flow.
