  • 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.
