    Abstract: Homo- and copolymers of isobutene are prepared by continuous cationic polymerization of isobutene or mixtures of isobutene with ethylenically unsaturated comonomers in the presence of an initiator system comprising:i) a Lewis acid selected from covalent metal-halogen compounds and covalent semimetal-halogen compounds andii) at least one aprotic organic compound I having at least one functional group FG which forms a carbocation or a cationic complex with the Lewis acid under polymerization conditions in an organic solvent inert with respect to the Lewis acid, by a process in which the polymerization is carried out in a tubular flow-through reactor which has a plurality of curves having an alternating direction of curvature.

    Abstract: A process for the functionalization of isobutene polymers comprises reaction of at least one isobutene polymer having terminal unsaturation with a hydroboration agent comprising the reaction product of a borane source with 0.5-1.8 equivalents of an alkene having a mol. wt. of less than 250.

    Abstract: A process for the preparation of polyisobutene containing at least 75 mol % of terminal vinylidene groups, in which isobutene or an isobutene-containing hydrocarbon mixture is polymerized in the liquid phase in the presence of a boron trifluoride complex catalyst having the composition a(BF3):b(Co1):c(Co2) where Co1 is at least one tertiary alcohol, Co2 is at least one compound selected from water, primary alcohols, secondary alcohols, dialkyl ethers, alkanecarboxylic acids and phenols, the ratio c:b is from 0.9 to 1.8 and the ratio (b+c):a is from 0.9 to 3.0, is described.
