An absorbent structure made at least in part from a superabsorbent material having a retention capacity (CRC) as determined by a Centrifuge Retention Capacity Test of at least about 25 g/g and a free swell gel bed permeability (GBP) as determined by a Free Swell Gel Bed Permeability Test of at least

An absorbent structure made at least in part from a superabsorbent material having a retention capacity (CRC) as determined by a Centrifuge Retention Capacity Test of at least about 25 g/g and a free swell gel bed permeability (GBP) as determined by a Free Swell Gel Bed Permeability Test of at least 575×10−9 cm2. In another embodiment, the absorbent structure is made at least in part from a superabsorbent material having a retention capacity (CRC) as determined by a Centrifuge Retention Capacity Test of at least about 25 g/g, an absorbency under load (AUL) at 0.9 psi as determined by an Absorbency Under Load Test of at least 18 and a free swell gel bed permeability (GBP) as determined by a Free Swell Gel Bed Permeability Test of at least about 350×10−9 cm2.

What is claimed is: 1. An absorbent structure comprising at least in part a superabsorbent material comprising a crosslinked superabsorbent polymer or combination of polymers comprising from about 55 to about 99.9 weight percent of polymerizable unsaturated acid group containing monomers and ethylenically unsaturated monomers which can be copolymerized with the polymerizable unsaturated acid group containing monomers and which are selected from acrylamidopropyltrimethylammonium chloride and ethoxylated (meth)-acrylates, the superabsorbent material having a retention capacity (CRC) as determined by a Centrifuge Retention Capacity Test of at least about 25 g/g and a free swell gel bed permeability (GBP) as determined by a Free Swell Gel Bed Permeability Test of at least 575 ×10−9 cm2, wherein the superabsorbent material in the absorbent structure comprises in the range of about 40 percent to about 60 percent of the weight of the absorbent structure.
