RUBBER COMPOSITION, RUBBER COMPOSITION FOR TIRE TREAD USE, CROSSLINKED RUBBER COMPOSITION, AND TIRE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition which is used for production of rubber having excellent abrasion resistance and crack growth resistance and includes a copolymer of a conjugated diene compound and a non-conjugated olefin, and a conjugated diene-based polymer; a rubber composition for tire tread use using the rubber composition for a tire tread member; a crosslinked rubber composition obtained by crosslinking the rubber composition; and a tire using the rubber composition or the crosslinked rubber composition.

SOLUTION: The rubber composition includes the copolymer of a conjugated diene compound and a non-conjugated olefin, and the conjugated diene-based polymer, wherein the content of cis-1,4 bonds in a moiety originating from the conjugated diene compound is greater than 92%.
