Abstract: A method for the production of isobutene polymers involves reacting isobutene with a halogen-, alkoxy- or acyloxy-substituted cyclopentene, cyclohexene or cycloheptene (I) in presence of a Lewis acid. A method for the production of isobutene polymers (PIB) involves reacting (a) isobutene and (b) a compound of formula (I). X = halogen, 1-6C alkoxy or 1-6C acyloxy; n = 1, 2 or 3. in presence of (c) a Lewis acid. An Independent claim is also included for isobutene polymers with at least one terminal group obtained by removing the group X from (I), or a functional derivative thereof obtained by hydrosilylation, hydrosulfonation, electrophilic aromatic substitution, epoxidation and optional reaction with nucleophiles, hydroboration and optional oxidative cleavage, reaction with enophiles in an En-reaction, addition of halogens or halogenated hydrocarbons, or hydroformylation.
