    Abstract: The production of polyisobutene by liquid-phase, cationic polymerization of isobutene in the presence of a boron trifluoride catalyst followed by the addition of a solid deactivator at a required point in time uses a deactivator (I) containing boron trifluoride-binding prim., sec., tert. and/or quat. nitrogen atoms, which is insoluble in the reaction mixture. In the production of polyisobutenes (PIB) by liquid-phase, cationic polymerization of isobutene or hydrocarbon streams containing isobutene in the presence of boron trifluoride as catalyst, the catalytic activity of the BF3 is partly or completely eliminated at a required point in time by means of a solid deactivator which contains BF3-binding prim., sec., tert. and/or quat. nitrogen atoms and is insoluble in the reaction mixture.

    Abstract: The invention relates to a method for deactivating and recovering boron trifluoride when producing polyisobutenes by means of cationic polymerization of isobutene or hydrocarbon streams containing isobutene in the liquid phase in the presence of boron trifluoride or in the form of a boron trifluoride catalyst complex. The catalyst complex is separated, essentially in the liquid phase, from the reactor discharge. The method comprises the following steps: a) removing from the polymerization reactor at -60 to 020 C., methanol, ethanol or a mixture of methanol and ethanol in such a quantity that an alcohol phase rich in boron trifluoride is formed; b) separating the alcohol phase according to (a) and, (c) optionally recycling the boron trifluoride of the alcohol phase obtained from (b) to the method in a suitable manner.

    Abstract: Polyisobutene is prepared by cationic polymerization of isobutene and/or isobutene-containing hydrocarbons in the liquid phase in the presence of a complex of BF3 and at least one cocatalyst which is preferably chosen from oxygen-containing compounds, the BF3/cocatalyst complex being produced in situ by adding BF3 and cocatalyst to a reaction stream, wherein BF3 and oxygen-containing cocatalyst are added to the reaction stream via a common binary nozzle comprising an outlet for BF3 and an outlet for the oxygen-containing cocatalyst. The invention also describes a binary nozzle having a centrally arranged outlet for the catalyst.

    Abstract: The invention relates to a method for producing highly reactive polyisobutenes containing over 80 mol.% terminal vinylidene groupings and with an average molecular weight of 500 to 5000 Dalton, by cationic polymerisation of isobutene in liquid phase in the presence of a complex consisting of boron trifluoride, at temperatures of +40 DEG C to 60 DEG C. According to said method, the polymerisation is carried out in the presence of a complex consisting of boron trifluoride and a) a primary alcohol with 1 to 20 C-atoms or a secondary alcohol with 3 to 20 C-atoms or a mixture of these alcohols and b) an ether which is free of tertiary alkyl groups, of formula (I) R -O-R wherein R and R are primary or secondary alkyl groups with 3 to 10 C-atoms, with the condition that at least one of the groups R and R is a secondary alkyl group.
