Patent ID: 8071202

Claim:
A water-absorbing polymer structure comprising: from about 0.001 wt % to about 10 wt % of a compound selected from a SiO compound or a trivalent cation or a combination of the SiO compound and trivalent cation; wherein said water-absorbing polymer structure has the following properties: a a retention determined according to the herein-described test method of at least 32 g/g; and b a Time-dependent Absorption Against a Pressure (TAAP at 0.3 psi) determined according to the test method described herein of 20 g/cm 2 , (TAAP; Time-dependent Absorption Against Pressure at 0.3 psi) selected from the group consisting of: b1 50% of the maximum absorption of the polymer structure within about 20 minutes and b2 90% of the maximum absorption of the polymer structure within about 40 minutes.
