(57) Abstract: A method for preparing a silyl-functional living cationic polymer that, when coupled, forms a water-curable telechelic system is disclosed. The method comprises reacting (A) at least one cationically polymerizable monomer with (B) a novel initiator in the presence of a Lewis acid. The initiator has the following formula: Wherein R is selected from an alkyl group having 1-10 carbon atoms or an aryl group having 6-18 carbon atoms, and R ′ is a divalent aliphatic hydrocarbon group having at least 3 carbon atoms. And X is a halogen, Y is selected from the group consisting of halogen, alkoxy, acyloxy, and hydroxyl groups, and a is 1, 2, or 3.]. |
