  • Functionalized nitrile rubbers and the production thereof
    Patent number: 10011664
    Abstract: Provided are new functionalized nitrile rubbers, which may optionally also be in partially or wholly hydrogenated form, and also a process for preparing them by metathesis of nitrile rubbers in the presence of a metathesis catalyst and at least one functionalized allyl compound. The new functionalized nitrile rubbers are suitable for producing vulcanizable mixtures and allow the production of vulcanizates having very stable networks. Also made possible, in particular, is the synthesis of block copolymers.
    Type: Grant
    Filed: January 25, 2012
    Date of Patent: July 3, 2018
    Assignee: ARLANXEO DEUTSCHLAND GMBH

  • Ruthenium-based complex catalysts
    Patent number: 9828401
    Abstract: The present invention provides novel Ruthenium-based transition metal complex catalysts comprising specific ligands, their preparation and their use in hydrogenation processes. Such complex catalysts are inexpensive, thermally robust, and olefin selective.
    Type: Grant

  • METHOD FOR PRODUCING PURIFIED NITRILE RUBBERS
    Publication number: 20140329982
    Abstract: A new process is provided for producing a purified nitrile rubber by subjecting the nitrile rubber, which contains specific impurities, to a defined ultrafiltration. Success is thereby achieved in substantially reducing the amount of the specific impurities in the nitrile rubber.
