Abstract: The invention relates to a method for producing mainly ethylenically unsaturated isobutene polymers, wherein the sum of proportions of molecules with a double bond in an α position and molecules with a double bond in a position β is increased to 75 %mol by polymerising isobutene in a liquid phase in the presence of a diluted or dispersed catalyst complex which comprises (i) an electron donor and (ii) a compound of general formula (I) Ha Meb [MFx]c, wherein Me is a metal with oxidation state m, M is an element selected from elements of the groups 2, 3, 4, 5, 10, 11, 13, 14 or 15 of the periodic table according to the IUPAC notation of an element oxidation number n, a is an integer ≥1, b is an integer ≥0, x is an integer ≥2 and c is [(a+mb)/(x-n)]. The catalyst is preferably embodied in the form of HBF4 O(CH3)2. The inventive method makes it possible to obtain an isobutene polymer having a low fluorine-content even using technical C4 hydrocarbon portions as an isobutene source.

Abstract: The invention relates to a method for processing a liquid reaction discharge of the cationic polymerisation of isobutene, which essentially consists of polyisobutene, unconverted isobutene and an inert diluent. According to said method, the reaction discharge is heated and expanded in an expansion chamber, whereby as a result of said expansion, the reaction discharge is separated into a liquid phase containing the polyisobutene and a gas phase containing the bulk of the isobutene contained in the reaction discharge and of the diluent.

Abstract: 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inlet located in the peripheral wall, and a finely dispersed mixture of the organic phase and the terminating agent is withdrawn via an outlet located in the peripheral wall and is delivered to a phase separation process.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.
