Abstract: The invention relates to polyalkene amine formulations comprising at least one polyalkene amine in a solvent. Said formulations have improved applicational properties, especially at low temperatures. The invention also relates to a method for the production of said formulations, in addition to the use thereof in fuel and lubrication compositions, especially fuels, in order to improve the effects of said fuel on the cleaning of the inlet system.

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inlet located in the peripheral wall, and a finely dispersed mixture of the organic phase and the terminating agent is withdrawn via an outlet located in the peripheral wall and is delivered to a phase separation process.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