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.

Abstract: Substituted 7- to 12-membered cycloalkanes which have leaving groups, in particular chlorine atoms, on tertiary ring carbons, a process for preparing them and their use as initiators for cationic polymerization, in particular the cationic polymerization of isobutene are described. Preferred compounds are 1,4-dichloro-1,4-dimethylcyclooctane, 1,5-dichloro-1,5-dimethylcyclooctane and mixtures thereof. They are prepared by addition of hydrogen chloride onto appropriately substituted cycloalkapolyenes.

Abstract: alpha-Chloroisopropyl-substituted aromatics are obtained in high yield by treating isopropenyl-substituted aromatics with hydrogen chloride gas in the absence of a solvent. The alpha-chloroisopropyl-substituted aromatics serve as initiators for the cationic polymerization of isobutene.

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: The invention relates to a method for producing homopolymers and copolymers of isobutene by the 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 among covalent metal- halogen compounds and covalent semimetal-halogen compounds; ii) at least one aprotic organic compound (I) having at least one functional group (FG) which , under polymerization conditions, forms a carbocation or a cationogenic compl ex with the Lewis acid, in an organic solvent that is inert to the Lewis acid. The inventive method is characterized in that the polymerization is carried out in a tubular continuous flow reactor that has a number of bends with an alternating bending direction.
