Publication number: 20070282074Abstract: An object of the present invention is to provide a process for producing an isobutylene block copolymer, which process can provide a resin having a low content of a catalyst residue and high transparency. The object can be achieved by a process for producing an isobutylene block copolymer by living cationic polymerization using a Lewis acid, wherein, for removing the Lewis acid from a solution after the polymerization, the solution is charged into and mixed with water in which a nonionic surfactant with an HLB of 10 or less is contained in an amount of 0.01 to 0.5 part by weight based on 100 parts by weight of the isobutylene block copolymer.Type: ApplicationFiled: April 7, 2005Publication date: December 6, 2007Inventors: Takanori Hatano, Ryuji Fukuda
