Abstract
The present invention provides a copolymer of a conjugated diene compound and a non-conjugated olefin, in which the conjugated diene unit has cis-1,4 bonds and the non-conjugated olefin contains many ethylene structures. In a copolymer of a conjugated diene compound and an unconjugated olefin other than the conjugated diene compound, the conjugated diene unit has a cis-1,4 bond content of 50% or more and the unconjugated olefin is contained in an amount of 20 mol % or more.
