  • 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

    Assignee: ARLANXEO Deutschland GmbH
    Inventors: Werner Obrecht, Christopher Ong, Julia Maria Jeschko, Oskar Nuyken
  • Patent number: 9428592
    Abstract: Provided are new partially hydrogenated nitrile rubbers which are distinguished by a specific ratio of viscosity to molecular weight, and also vulcanizable mixtures and vulcanizates based on said rubbers, and also the associated preparation processes. The partially hydrogenated nitrile rubbers lead to compounded formulations having advantageous processing properties in conjunction with excellent vulcanizate properties.
