  • PRODUCTION OF DISPERSANTS BY NITROXIDE-MEDIATED SOLUTION POLYMERIZATION
    Publication number: 20210261711
    Abstract: Methods for using a copolymer, especially as a dispersant for solid particles, in particular as a dispersant for mineral binder compositions, where the copolymer is obtained from ionizable monomers m1 and side chain-bearing monomers m2 that are polymerized by nitroxide-mediated solution polymerization to give the copolymer, wherein the polymerization is conducted in the presence of an agent including a carboxyl group-bearing and phosphated alkoxy amine.
    Type: Application
    Filed: May 10, 2021
    Publication date: August 26, 2021
    Applicant: SIKA TECHNOLOGY AG
    Inventors: Jürg WEIDMANN, Fabia ULBER, Jörg ZIMMERMANN
