Procedure: In a 2 L reaction vessel equipped with a stirrer, 589 mL of methylcyclohexane (dried over molecular sieves), 613 mL of n-butyl chloride (dried over molecular sieves) and 0.550 g of cumyl chloride were charged. After cooling the reaction vessel to −70° C., 0.35 mL of a-picoline (2-methylpyridine) and 179 mL of isobutylene were added. Further, 9.4 mL of titanium tetrachloride was added to start polymerization, and then the solution was reacted for 2.0 hours while being stirred at −70° C. Next, 59 mL of styrene was added into the reaction vessel and the reaction was continued for 60 minutes, and then the reaction was terminated by adding a large amount of methanol. After removing the solvent and the like from the reaction solution, a polymer was dissolved in toluene and washed twice with water. This toluene solution was added to the methanol mixture, thereby precipitating a polymer, and the resultant polymer was dried at 60° C. for 24 hours to obtain a styrene-isobutylene diblock copolymer. In a 2 L reaction vessel equipped with a stirrer polymerization the solution was reacted for 2.0 hours the reaction was terminated by adding a large amount of methanol After removing the solvent the like from the reaction solution, a polymer was dissolved in toluene washed twice with water This toluene solution was added to the methanol mixture precipitating a polymer the resultant polymer was dried at 60° C. for 24 hours

After cooling the reaction vessel to −70° C., 0.35 mL of α-picoline (2-methylpyridine) and 179 mL of isobutylene were added. Further, 9.4 mL of titanium tetrachloride was added to start polymerization, and then the solution was reacted for 2.0 hours while being stirred at −0.70° C.

Procedure: 4.644 g (0.03 mol) of α,α-dimethylbenzyl chloride and 2.373 g (0.03 mol) of pyridine were reacted in 40 ml of methanol at 40° C. for 3 days. After the reaction, the solvent was evaporated in vacuo and ether-water was added to the residue to extract unreacted reactants in the etherial layer. To the aqueous layer was added 7.7 g (0.03 mol) of sodium hexafluoroantimonate. The resulting crystals were suction filtered, washed and dried to give the title compound. After the reaction the solvent was evaporated in vacuo and ether-water was added to the residue to extract unreacted reactants in the etherial layer filtered washed dried
