Method for producing isobutylene block copolymer |
| abstract |
An object of the present invention is to provide a process for producing an isobutylene-based block copolymer with a small amount of catalyst residue and a highly transparent resin. A method for producing an isobutylene block copolymer by living cationic polymerization using a Lewis acid, wherein when the Lewis acid is removed from the solution after polymerization, an HLB value of 10 or less with respect to 100 parts by weight of the isobutylene block copolymer This can be achieved by a method for producing an isobutylene block copolymer, wherein the nonionic surfactant is added to water to which 0.01 to 0.5 parts by weight of water is added and mixed. |
