  • Process for the production of highly reactive polyisobutenes
    Patent number: 7291758
    Abstract: The present invention relates to a process for the production of highly reactive polyisobutenes with a content of terminal vinylidene groupings of greater than 80 mol % and an average molecular weight of 500 to 10,000 Dalton by cationic polymerization of isobutene or of isobutene and monomers copolymerizable with isobutene in the presence of solvent-stabilized transition metal complexes with weakly coordinated anions.
    Type: Grant
    Filed: April 4, 2006
    Date of Patent: November 6, 2007
    Assignee: Basf Aktiengesellschaft
    Inventors: Martin Bohnenpoll, Jürgen Ismeier, Oskar Nuyken, Mario Vierle, Dirk Kurt Schön, Fritz Kühn
