Patent ID: 7662460

Claim:
A absorbent sheet consisting essentially of: (a) a superabsorbent polymer component, as particles, comprising (i) at least one unneutralized acidic water-absorbing resin, and (ii) at least one unneutralized basic water-absorbing resin, wherein the superabsorbent polymer component is free of interparticle crosslinking; and (b) a plasticizing component in an amount of about 0.1 to about 200 parts by weight per 100 weight parts of the superabsorbent polymer component, wherein the sheet contains about 60% to 100%, by weight, of (a) and (b), wherein the sheet material is flexible and has a density of about 0.65 to about 0.85 g/cc, and wherein the plasticizing component is present essentially in its unreacted form.
