FIELD: chemistry.
SUBSTANCE: copolymer of conjugated diene compound and non-conjugated olefin includes block-copolymer, with peak area in range 70-110°C, constituting, at least, 60% of peak area in range 40-140°C, and with peak area in range 110-140°C, constituting 20% or less of peak area in range 40-140°C, where areas of peaks are measured by method of differential scanning calorimetry (DSC) in accordance with JIS K 7121-1987. Also claimed are copolymer-including rubber mixture, cross-linked rubber mixture and tyre.
EFFECT: copolymers possess high fatigue strength, low heat release and sufficient relative elongation at break.
