  • Superabsorbent polymer having delayed free water absorption
    Patent number: 7579402
    Abstract: The present invention is directed to a coated superabsorbent polymer comprising a coated superabsorbent polymer having a delayed free water absorption property of absorbing about 13 grams or less of water per gram of superabsorbent polymer in about 15 seconds. The present invention is directed to a coated superabsorbent polymer having delayed water absorption comprising a) a composition comprising from about 55 to about 99.9 wt. % of polymerizable unsaturated acid group containing monomers; and from about 0.001 to about 5.0 wt. % of internal crosslinking agent; wherein the composition has a degree of neutralization of more than about 20%; and b) a salt coated on the composition.

  • Cellulose material with improved absorbency
    Patent number: 7482058
    Abstract: An absorbent cellulose material having an application of superabsorbent polymer adhered to the cellulose material. In particular, the cellulose material has an application of pre-superabsorbent polymer adhered to the material, wherein an aqueous solution of pre-superabsorbent polymer is applied to the cellulose material and converted to superabsorbent polymer upon subjected to heat for a sufficient time. The absorbent cellulose material has a fluid retention of greater then 2 g/g.
