PROBLEM TO BE SOLVED: To provide a rubber for producing a vulcanized rubber having improved dynamic vibration isolation, improved mechanical strength and improved wear behavior. SOLUTION: The rubber is composed of a diolefin, bonded via a sulfur atom, and a non-polar side group saturated linear, branched or cyclic hydrocarbon group having 1 to 22 carbon atoms or 6 to 22 carbon atoms. It has non-polar pendant aromatic hydrocarbon groups having carbon atoms in a content of 0.1 to 40% by weight based on the total amount of rubber, and is prepared by solution polymerization. |
