FIELD: chemistry.
SUBSTANCE: invention relates to functionalised diene polymers. Disclosed is a method of producing a functionalised polymer, involving the stages: (i) polymerisation of conjugated diene monomer using anionic initiator to obtain reactive polymer; and (ii) reacting the reactive polymer with a carboxylic ester or carboxylic acid, containing a silylated amine group, where silylated amino group is directly connected to the fragment, selected from a group consisting of acyclic fragments, heterocyclic fragments and non-aromatic cyclic fragments.
EFFECT: technical result is disclosed method enables to obtain functionalised polymers with low hysteresis providing improved characteristics of the tires made thereof.
