COPOLYMER, RUBBER MIXTURE, CROSS-LINKED RUBBER MIXTURE AND TYRE Russian patent published in 2015 - IPC C08F297/06 C08L53/00 C08K3/00 B60C1/00 

Abstract RU 2553474 C1

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.
