Document Type and Number:
Japanese Patent JP5731216
Kind Code:
B2
Abstract:
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.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%.
