FIELD: polymers.
SUBSTANCE: polymers based on conjugated diene and rubber compositions based on them. Conjugated diene polymer subjected to a coupling reaction is provided for use in a rubber composition having a Mooney viscosity measured at 100°C, in the range from 40 or more to 170 or less and measured at 100°C a Mooney stress relaxation of 0.35 or less, and characterized by a branching number (Bn) measured according to light scattering measurement using the GPC method with a viscosity detector of 8 or more. A method for producing said polymer, a composition based on it for use in a rubber composition, and a rubber composition are also proposed.
EFFECT: proposed polymer is characterized by excellent processing capability of the vulcanizate obtained from it, as well as abrasion resistance and fracture strength of the resulting material.
