Abstract: A process for the preparation of polyalkenylsuccinimide products, in particular polyisobutenylsuccinimide products, is proposed, in which a polyalkene is reacted with a maleic acid, maleic anhydride or a functional derivative thereof to give a polyalkenylsuccinic anhydride and the polyalkenylsuccinic anhydride is then reacted with an oligoamine or polyamine, the polyalkenylsuccinic anhydride either (a) first being reacted with an alcohol or phenol and, without isolation of the reaction product, then with the oligoamine or polyamine, or (b) the polyalkenylsuccinic anhydride being reacted with the oligoamine or polyamine in the presence of an alcohol or phenol and (c) if desired, the alcohol or the phenol then being removed. Novel polyalkenylsuccinimide products, in particular polyisobutenylsuccinimide products, and fuel additives are also proposed.

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.
