Abstract
Disclosed are polymeric foam structures suitable for absorbing and storing body fluids such as urine, menses and the like. These liquid storage structures are high suction collapsible polymeric foam materials. The collapsed foams, upon contact with aqueous fluids, can absorb and expand these fluids even when opposed by significant hydrostatic pressures. These absorbent polymeric foams comprise interconnected open-cells. In one aspect, the foams can absorb at least about 25 g/g against a hydrostatic head pressure of 50 cm. In another aspect, the foams of the present invention will have a vertical hang sorption height at 90%
of at least about 60 cm.
of at least about 60 cm.
