FIELD: chemistry.

SUBSTANCE: present invention relates to polymer based on conjugate diene. Polymer based on conjugate diene has absolute molecular weight measured using determination of light dissipation in gel-penetrating chromatography (hereinafter – GPC) with a viscosity detector, equal to from 100×10⁴ to 5000×10⁴, and has a number of branches (Bn), measured using determination of light dissipation in GPC with a viscosity detector, equal to from 8 to 84.

EFFECT: development of polymer based conjugate diene, which would have excellent capability of processing in case of using it for the production of vulcanized rubber, and which, in the form of vulcanized rubber, would have excellent balance between a property of low hysteresis losses and slipping resistance on a wet road, as well as abrasion resistance, and would have practically sufficient destruction characteristics.
