PROBLEM TO BE SOLVED: To provide a rubber composition which is significantly improved in grip characteristics, applicable to a tire tread part and improved in viscoelastic behavior.SOLUTION: There are provided an isobutylene-based copolymer containing β-pinene as a copolymer; an isobutylene-based copolymer obtained by hydrosilylation of a part of an unsaturated bond part derived from β-pinene of the isobutylene-based copolymer; and a rubber composition comprising silica and an unsaturated rubber. In addition, there is provided a crosslinked rubber composition obtained by crosslinking the rubber composition.SELECTED DRAWING: None
