Patent ID: 8403904

Claim:
An absorbent article comprising: (a) a liquid pervious topsheet; (b) a liquid impervious backsheet; (c) a core positioned between (a) and (b), said core comprising about 10% to 100% by weight of a particulate superabsorbent polymer and 0% to about 90% by weight of hydrophilic fiber material; (d) optionally a tissue layer positioned directly above and below said core (c); and (e) an acquisition layer positioned between (a) and (c); wherein the particulate superabsorbent polymer comprises a monomer selected from an ethylenically unsaturated carboxylic acid, ethylenically unsaturated carboxylic acid anhydride, salts or derivatives thereof, and an internal crosslinker agent wherein the internal crosslinker agent comprises a silane compound comprising at least one vinyl group or allyl group and at least one Si—O bond wherein the vinyl group or allyl group is directly attached to a silicon atom, wherein the superabsorbent polymer has a Centrifuge Retention Capacity Increase of 2 g/g or more based on CRC Increase=CRC(rt,5 hr)−CRC(rt,0.5 hr) and wherein CRC Increase measures the increase in the CRC that occurs and is calculated as the difference between the second CRC and first CRC and rt refers to room temperature.
