<p><P>PROBLEM TO BE SOLVED: To provide a rubber composition which is used for manufacturing a rubber excellent in roll processability and bending fatigue resistance, and contains a block copolymer of a conjugated diene compound and a non-conjugated olefin, and a random copolymer in which monomer units of the conjugated diene compound and the non-conjugated olefin are irregularly arranged; and to provide a crosslinked rubber composition obtained by crosslinking the rubber composition, and a tire using the rubber composition or the crosslinked rubber composition. <P>SOLUTION: The rubber composition contains the block copolymer of the conjugated diene compound and the non-conjugated olefin, and the random copolymer in which the monomer units of the conjugated diene compound and the non-conjugated olefin are irregularly arranged, wherein the mass ratio of the block copolymer and the random copolymer is preferably in the range of 95/5 to 5/95. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
