摘要：
The present invention provides a copolymer of a conjugated diene compound and a non-conjugated olefin that is used for manufacturing rubber excellent in low heat generation properties, heat resistance, ozone resistance (weather resistance), a rubber composition containing the copolymer, a crosslinked rubber composition obtained by crosslinking the rubber composition, and a tire manufactured by using the rubber composition or the crosslinked rubber composition. In the copolymer of a conjugated diene compound and a non-conjugated olefin, the content of 1,2 adduct units (including 3,4 adduct units) of a unit derived from the conjugated diene compound is 5% or less.
