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.
