<p><P>PROBLEM TO BE SOLVED: To provide a rubber composition which is used for manufacturing a rubber high in roll processability and breaking strength, and contains an alternating copolymer of a conjugated diene compound and a non-conjugated olefin, and a block copolymer of the conjugated diene compound and the non-conjugated olefin; 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 alternating copolymer of the conjugated diene compound and the non-conjugated olefin, and the block copolymer of the conjugated diene compound and the non-conjugated olefin, wherein the mass ratio of the alternating copolymer and the block copolymer is preferably in the range of 80/20 to 3/97. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
