Abstract: A method of making functional polyisobutylene (PIB)-containing oligomers and polymers. By the disclosed method, the synthesis of functional PIB-containing polymers can be achieved directly under cationic polymerization conditions and does not include any post-polymerization reactions. The desired functionality is introduced by direct Electrophilic Aromatic Substitution (EAS) reaction using substituted phenyl ring carrying desirable functionalities that do not react with Lewis acid but have weak association with Lewis acid, which still allow living polymerization and EAS reaction under living cationic polymerization conditions. In the disclosed method functional polyisobutylene or isobutylene containing oligomers and polymers can be prepared using stoichiometric or near stoichiometric ratios of the capping or functionalization reagent to polymer end-chain.
