  • Synthesis of improved binders and modified tacticity
    Patent number: 8426497
    Abstract: The invention relates to a process for preparing polymers for coating applications by polymerizing esters of acrylic acid or of methacrylic acid or vinyl aromatics or other free-radically polymerizable vinyl compounds or monomer mixtures composed predominantly of such monomers by means of a continuous polymerization process. In particular, the invention relates to a solvent-free preparation process for polymers, through which the binder can be prepared for coating applications with superior processing properties, very good thermal stability, improved pigment wetting and a higher gloss.
    Type: Grant
    Filed: February 2, 2009
    Date of Patent: April 23, 2013
    Assignee: Evonik Roehm GmbH
    Inventors: Helmut Schwind, Uwe-Martin Wiesler, Cornelia Borgmann, Heike Leuninger, Thomas Schmied, Stefanie Maus, Werner Friedrich, Sven Balk
