    摘要: The invention relates to a method for producing polyisobutenes, in which isobutene is polymerized in liquid organic phase in the presence of a Lewis acid catalyst, the organic phase is mixed with an aqueous terminating agent in a dynamic mixer in order to terminate the reaction, said dynamic mixer comprising an axially symmetrical mixing chamber formed by a peripheral wall and two end walls as well as a mixing rotor that is rotatably driven therein. The organic phase is introduced via a first inlet located in the peripheral wall while the aqueous terminating agent is introduced via a second inlet located in the peripheral wall, and a finely dispersed mixture of the organic phase and the terminating agent is withdrawn via an outlet located in the peripheral wall and is delivered to a phase separation process. The inventive method is used for producing highly reactive polyisobutenes and/or polyisobutenes having a narrow molecular weight distribution.

    摘要: The invention relates to the production of isobutylene homopolymers having a weight-average molecular weight of 75,000 to 10,000,000 by means of the polymerization of isobutylene by (a) performing the polymerization at -80°C to -190°C, (b) using optionally halogenated C
    1 to C
    5 hydrocarbons as an inert solvent, (c) using a Lewis acid complex as a polymerization catalyst, and (d) performing the polymerization in the presence of at least one reaction accelerator in the form of an ethylenically saturated hydrocarbon compound, which contains an oxygen atom and no proton that can be emitted, and performing the polymerization in the presence of at least one chain length regulator, which contains a tertiary olefinic carbon atom.
