    摘要： A durable, conformable, absorbent, hydrophilic, polymeric latex foam composition having a free absorbent capacity of at least 5 grams of a 0.9 weight percent aqueous saline solution per gram of foam and capable of vertically wicking said aqueous saline solution to a height of greater than about 5 cm. In a preferred embodiment, after compression, the latex foam composition remains thin until wet, whereupon it expands and exhibits a high free absorbent capacity and high vertical wicking height.

    摘要： The present invention refers to a high internal phase polyelectrolyte emulsions which are useful for the manufacture of superabsorbent polymers having two phases: i) a continuous oil phase and the ii) a dispersed aqueous phase containing the aqueous monomer solution prior to polymerization and the polyelectrolyte in water-soluble, or water-swellable or very slightly crosslinked form after polymerization, wherein the polymerization occurs in the dispersed aqueous phase and wherein the dispersed aqueous phase contains a high concentration of polyelectrolyte. The present invention also refers to a process for preparing such emulsions and for inverting these emulsions so as to form films or other patterns of the superabsorbent polymer. Absorbent structures containing SAP films or other patterns prepared by the present invention are also contemplated.
