    Abstract: A process is described for preparing polyisobutene having a low halogen content, in which isobutene is polymerized in the presence of a catalyst which comprises a halogenated Lewis acid, the catalyst is removed and/or deactivated, and the resulting polyisobutene is contacted with a zeolite of an average pore size of from 5 to 15 Å.

    Abstract: The present invention relates to a process for preparing polyisobutenes by polymerizing isobutene in the presence of a Lewis acid catalyst in liquid organic phase, terminating the reaction by admixing the organic phase with an aqueous terminator in a dynamic mixer which has a rotationally symmetric mixing chamber formed from one circumferential wall and two end walls, and a mixing rotor driven such that it rotates therein, the organic phase being introduced through a first inlet orifice provided in the circumferential wall and the aqueous terminator via a second inlet orifice provided in the circumferential wall, and removing a finely dispersed mixture of the organic phase and of the terminator through an outlet orifice provided in the circumferential wall and feeding it to a phase separation. The process serves to prepare high-reactivity polyisobutenes and/or polyisobutenes with narrow molecular weight distribution.

    Abstract: New polyisobutyl derivatives (I) consist of a polyisobutyl moiety bonded to the heteroatom of a cyclic ammonio or acyclic or cyclic phosphonio, oxonio, sulfonio or selenio group. Polyisobutyl derivatives of formula PIB-X +>. Y ->(I) are new. PIB : polyisobutyl; X +>N-bonded 5-7 membered saturated, partially saturated or aromatic heterocyclic ammonio group (optionally containing additional heteroatoms and optionally substituted (os)), -N +>R 1>R 2>R 3>, -P +>R 4>R 5>R 6>, -O +>R 7>R 8>, -S +>R 9>R 1> 0>or -Se +>R 1> 1>R 1> 2>; R 1>- R 1> 2>H, alkyl, -A-OA, hydroxyalkyl, alkenyl, alkynyl, cycloalkyl, aryl, -A-aryl or Het (where hydrocarbyl or heterocyclyl moieties are os); or PR 4>R 5>, OR 7>R 8>, SR 9>R 1> 0>or SeR 1> 1>R 1> 1>heterocycle (os and optionally containing additional heteroatoms); Y ->halide anion or Lewis acid-Lewis base adduct of formula (M aZ b) ->; M : B, Al, Ti, V, Fe, Zn, Cu, Sn, Ga, Zr, Mo, Nb, Sb or In; Z : F, Cl oder Br; a : 1-3; b : 2-10; An independent claim is included for the production of homo- or copolymers of cationically polymerizable olefinically unsaturated monomer(s) (II) by polymerization in presence of (I), provided that in the case of (I; Y ->= halide or Lewis acid-Lewis base adduct in which a = 1) the polymerization is carried out in presence of a Lewis acid.
