Abstract:
A hydrogel-forming polymeric material comprising a first compound which is a superabsorbent polymer and a second compound present in the first as a dispersed phase comprising an elastomeric material effective to increase the fracture resistance of the superabsorbent prepared from:a. a first compound comprising carboxylic-functional polyelectrolytes in combination with a crosslinker reactive with carboxyl or carboxylate groups; and b. an effective amount of a second compound comprising an aqueous dispersion of a rubbery material, wherein the hydrogel-forming polymeric material exhibits a gel capacity of at least about 20 grams 0.9% saline per gram of material and a Friability Index of at least about 25% greater than the Friability Index exhibited by a hydrogel-forming polymeric material that is prepared without the second compound.
