Abstract: Production of polyisobutene involves polymerization of isobutene (I) using an inert diluent and a Lewis acid (II) containing halogen as catalyst, in which (I) in the form of droplets is contacted with (II) in polymerization equipment. Independent claims are included for (1) polyisobutene with a number average molecular weight Mn in the range of 150000-5000000 g/mole and a dispersity index D in the 4-10 range; (2) polyisobutene obtained by the specified process.

Abstract: Production of polyisobutene (I) from a starting 4C hydrocarbon stream (II), containing isobutene, 1-butene and 2-butene, includes: (a) distillatively separating (II) into a more volatile fraction (F1) (containing most of the isobutene and 1-butene in (II)) and a less volatile fraction (F2) (containing most of the 2-butene); and (b) subjecting the 1-butene in (F1) to chemically selective reaction and separating the reaction products from the remaining components of (F1).

Abstract: The production of polyisobutene by liquid-phase, cationic polymerization of isobutene in the presence of a boron trifluoride catalyst followed by the addition of a solid deactivator at a required point in time uses a deactivator (I) containing boron trifluoride-binding prim., sec., tert. and/or quat. nitrogen atoms, which is insoluble in the reaction mixture. In the production of polyisobutenes (PIB) by liquid-phase, cationic polymerization of isobutene or hydrocarbon streams containing isobutene in the presence of boron trifluoride as catalyst, the catalytic activity of the BF3 is partly or completely eliminated at a required point in time by means of a solid deactivator which contains BF3-binding prim., sec., tert. and/or quat. nitrogen atoms and is insoluble in the reaction mixture.

Abstract: A process for the preparation of polyisobutylenes by cationic polymerization of isobutylene or isobutylene-containing hydrocarbon streams in the liquid phase in the presence of boron trifluoride acting as catalyst, the catalytic activity of boron trifluoride being partially or completely stopped by means of a solid deactivator following a given timelapse, which deactivator is an inorganic, anhydrous or hydrous oxygen compound of aluminum which is insoluble in the reaction mixture.
