FIELD: chemistry.
SUBSTANCE: invention relates to polymers that are suitable for use in making rubber articles, such as tyre treads. The method of producing a functionalised polymer involves conducting a reaction between a polymer with an active terminal group, which contains a diene monomer moiety, and a compound which contains a disilylamino group and a group which is capable of reacting with polymers with an active terminal group selected from keto, thioketo, epoxy and epithio groups. The polymer contains a diene monomer moiety and a terminal moiety which contains a disilylamino group and a residue of a group which contains a heteroatom. Said terminal moiety has the general formula 
, where values of radicals are given in the claim. Also disclosed is a vulcanisate which contains said polymer, and an article made therefrom.
EFFECT: said polymers and articles made therefrom are characterised by improved tensile properties, improved wear resistance and fatigue resistance and low hysteresis loss.
