    摘要： 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.
