Abstract
The present invention provides a random copolymer that is used for manufacturing a rubber having high fracture strength and excellent low loss properties (low heat generation properties) and that includes randomly arranged monomer units of a conjugated diene compound and of a non-conjugated olefin, a rubber composition containing the random copolymer, a cross-linked rubber composition obtained by crosslinking the rubber composition, and a tire manufactured by using the rubber composition or the cross-linked rubber composition. A copolymer of a conjugated diene compound and a non-conjugated olefin includes a random copolymer having randomly arranged monomer units of the conjugated diene compound and of the non-conjugated olefin, which random copolymer contains, by at least 5 mol %, alternate bonding units of the conjugated diene compound and the non-conjugated olefin in a unit derived from the non-conjugated olefin.
