<p><P>PROBLEM TO BE SOLVED: To provide: a copolymer of a conjugated diene compound and a non-conjugated olefin, wherein the copolymer is used for producing a rubber excellent in wettability, low-temperature properties, and weatherability, and contains cis-1,4 bonds at a moiety derived from the conjugated diene compound; a rubber composition that contains the copolymer; a crosslinked rubber composition obtained by crosslinking the rubber composition; and a tire obtained by using the rubber composition and the crosslinked rubber composition. <P>SOLUTION: In the copolymer of the conjugated diene compound and the non-conjugated olefin, the content of the cis-1,4 bonds at the moiety derived from the conjugated diene compound is lower than 92%, and the content of a moiety derived from the non-conjugated olefin is lower than 10 mol%. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
