  • Polyisobutene polyol and moulding compound
    Patent number: 7847020
    Abstract: An isobutene polymer which has an average of at least 1.4 terminal 1,3-propanediol groups is described, as is a crosslinking product thereof. Suitable crosslinkers are difunctional or higher-functionality isocyanates or epoxy compounds having at least two epoxide groups. The crosslinking products exhibit high storage moduli even at elevated temperatures.
    Type: Grant
    Filed: August 28, 2006
    Date of Patent: December 7, 2010
    Assignee: BASF Aktiengesellschaft
    Inventors: Hans Peter Rath, Arno Lange, Helmut Mach, J. Richard Blackborow
  • PREPARATION OF REACTIVE, ESSENTIALLY HALOGEN-FREE POLYISOBUTENES FROM C4-HYDROCARBON MIXTURES WHICH ARE LOW IN ISOBUTENE
    Publication number: 20100234542
    Abstract: The present invention relates to a process for preparing reactive and essentially halogen-free, especially fluorine-free, polyisobutenes from low-isobutene C4 hydro-carbon mixtures.
    Type: Application
    Filed: June 5, 2007

  • Epoxidation of isobutene polymers
    Patent number: 7741410
    Abstract: A process is described for epoxidizing an ethylenically unsaturated isobutene polymer, in which an organic phase comprising the isobutene polymer is contacted with an aqueous phase which comprises formic acid and hydrogen peroxide. The process affords essentially quantitative conversions after a short reaction time.
