  • MACROMOLECULAR KETOALDEHYDES
    Publication number: 20090223899
    Abstract: Methods of producing macromolecular compositions and using same are provided. The method includes preparing a resin material; forming an acetyl group on the resin material; and oxidizing the acetyl group via a one-step reaction including reacting a sulfoxide and an acid with the acetyl group to form a ketoaldehyde group. The macromolecular compositions are capable of removing an effective amount of one or more constituents from a physiological solution, such as urea during dialysis therapy.
    Type: Application
    Filed: May 13, 2009
    Publication date: September 10, 2009
    Applicants: Baxter International Inc., Baxter Healthcare S.A.
    Inventors: Mitchell J. Poss, Henk Blom, Alex Odufu, Robert Smakman
