Abstract
The present invention has its object to provide an isobutylene group block copolymer containing a highly reactive alkenyl group with a high rate of introduction of an alkenyl, and process for producing the same.An alkenyl-group-containing isobutylene group block copolymer comprising a polymer block derived from (a) a monomer component containing isobutylene group as a predominant monomer and (b) a monomer component not containing isobutylene group as a predominant monomer, in which said block copolymer has an alkenyl group of the following general formula (1).
