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.
