  • Recycled superabsorbent polymer particles
    Patent number: 8766032
    Abstract: The present invention relates to absorbent cores comprising recycled superabsorbent polymer particles which have previously been immobilized by a solidified thermoplastic composition. The superabsorbent polymer particles can be separated from the solidified thermoplastic composition by using a supercritical fluid such as carbon dioxide, propane or mixtures thereof.
    Type: Grant
    Filed: February 25, 2011
    Date of Patent: July 1, 2014
    Assignee: The Procter & Gamble Company
    Inventors: Marion Michnacs, Carsten Luckert, Carsten Zetzl
  • Method of separating superabsorbent polymer particles from a solidified thermoplastic composition comprising polymers
    Patent number: 8252848
    Abstract: A method for re-mobilizing superabsorbent polymer particles which have previously been immobilized by a solidified thermoplastic composition comprising at least 30 weight-% of a thermoplastic polymer. The superabsorbent polymer particles are separated from the solidified thermoplastic composition by using a supercritical fluid comprising carbon dioxide, propane, or mixtures thereof. Separation may be further improved by the use of one or more co-solvents.
