    Abstract: Polyisobutenes in which at least 60 mol % of the polymer chains have at least one olefinically unsaturated terminal group are prepared by cationic polymerization of isobutene or isobutene-containing monomer mixtures in the condensed phase by a process in which the polymerization is carried out in the presence of an initiator system comprising i) a Lewis acid selected from covalent metal chlorides and semimetal chlorides and ii) at least one organic compound I having at least one functional group FG which forms a carbocation or a cationic complex with the Lewis acid under the polymerization conditions, where FG is selected from acyloxy, alkoxy and halogen, which are bonded to a secondary or tertiary carbon atom or to an allylic or a benzylic carbon atom, in a solvent inert toward the Lewis acid, the Lewis acid being used in less than the stoichiometric amount, based on the functional groups FG.

    Abstract: Polyisobutenylphenols are prepared by alkylating an aromatic hydroxy compound with substantially monoethylenically unsaturated and substantially homopolymeric polyisobutenes in the presence of a Lewis acid alkylation catalyst by a process in which the polyisobutenes have a beta double bond content of at least 35 mol %.

    Abstract: A process for the preparation of polyisobutylenes by cationic polymerization of isobutylene or isobutylene-containing hydrocarbon streams in the liquid phase in the presence of boron trifluoride acting as catalyst, the catalytic activity of boron trifluoride being partially or completely stopped by means of a solid deactivator following a given timelapse, which deactivator is an inorganic, anhydrous or hydrous oxygen compound of aluminum which is insoluble in the reaction mixture.

    Abstract: Polyisobutenes are prepared by the continuous preparation process, by polymerizing isobutene in the presence of a catalyst comprising boron trifluoride and at least one cocatalyst in an inert organic solvent,a) a part of the reaction mixture obtained thereby being discharged continuously from the polymerization reactor,b) the catalyst being separated from the discharge and/or being deactivated in the discharge, andc) the solvent and any unconverted isobutene being separated from the discharge and recycled to the polymerization reactor,wherein the recycled solvent and, if present, the isobutene are subjected to a wash with water before recycling to the polymerization reactor and are then dried.
