Abstract: A process is described for preparing polyisobutene having a content of terminal vinylidene groups of at least 75 mol % by polymerizing isobutene or isobutenic hydrocarbon mixtures in the liquid phase in the presence of a boron trifluoride complex catalyst of the composition (BF 3 ) a .L 1 b .L 2 c .L 3 d where L 1 is water, a primary C 1 -C 5 -alkanol and/or a secondary C 3 -C 5 -alkanol, L 2 is at least one aldehyde and/or one ketone, L 3 is an ether having at least 5 carbon atoms, a secondary alkanol having at least 6 carbon atoms, a primary alkanol having at least 6 carbon atoms and/or a tertiary alkanol, the b:a ratio is in the range from 0.9 to 3.0, the c:a ratio is in the range from 0.01 to 0.5, and the d:a ratio is in the range from 0 to 1.0.

Abstract: Production of polyisobutene with number average molecular weight Mn 400-50000 and over 50 mole-% methylidene groups by polymerization of a reaction mixture containing isobutene in the presence of a catalyst containing boron trifluoride, is carried out at least partly in the presence of hydrogen cyanide or a cyanide or nitrile as moderator (I) and/or the reaction mixture is contacted with an inorganic adsorbent after polymerization in the presence of (I).

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.
