(Formula 1)n n n n n n n n A process for preparing monofunctional active cationic polymers which can be subsequently bonded to form a water-curable telechelic system is disclosed, which method comprises (A) at least one cationic polymerizable monomer and (B) in the presence of Lewis acid. Reacting the initiator of Formula 1, wherein R is selected from an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 10 carbon atoms, R 'is a divalent aliphatic hydrocarbon group having at least 3 carbon atoms, X is halogen, Y is selected from the group consisting of halogen, alkoxy, acyloxy and hydroxyl groups, and a is 1, 2 or 3. |
