Verfahren zur Herstellung von Polyisobutenen |
摘要 |
The invention relates to a method for producing polyisobutenes by means of cationic polymerisation of isobutene or hydrocarbon flows containing isobutene in the liquid phase in the presence of boron trifluoride as a catalyst. The catalytic efficacy of the boron trifluoride is partially or fully eliminated at a desired point in time by means of a solid deactivator, said deactivator being an inorganic, anhydrous, or aqueous aluminium oxide which is insoluble in the reaction mixture.
