摘要: Provided is a block copolymer of conjugated diene compound and non-conjugated olefin, rubber composition including the copolymer, crosslinked obtained by crosslinking composition, tire using or composition. The present invention having peak area in temperature range 70° C. to 110° that accounts for at least 60% 40° 140° 20% less C., areas being measured differential scanning calorimetry (DSC) according JIS K 7121-1987.
