摘要： Absorbent articles such as sanitary napkins, panty liners, adult incontinence devices, and the like are disclosed. The absorbent articles described herein comprise a foam absorbent structure comprising a hydrophilic, flexible, nonionic polymeric foam structure of interconnected open cells which is particularly suitable for absorbing blood and blood-based liquids. The foam structure is resiliently compressible and has resistance to compression deflection of from about 5% to about 85% when measured under a confining pressure of 0.74 psi at 31 DEG C. after 15 minutes. In preferred embodiments, the foam structure is compressible under such forces that when it is placed in the space between the wearer's labia majora, it will be compressed without deforming the wearer's labia majora, and will be molded by the wearer's labia and conform to the shape thereof. The absorbent structure may comprise an acquisition/fit portion and a storage portion wherein the acquisition/fit portion has softer mechanical properties than the storage portion, and is a capillary gradient in the direction of the storage portion.

摘要： Foams capable of absorbing blood and blood-based fluids, especially menses. These absorbent foams have high capillary absorption pressures required of absorbents used in catamenial products, yet have sufficient openness to allow free movement of the insoluble components in blood-based fluids such as menses. These absorbent foams are made by polymerizing high internal phase emulsions (HIPEs) where the volume to weight ratio of the water phase to the oil phase is in the range of from about 20:1 to about 125:1. These foams are particularly useful as absorbent members for catamenial pads.

摘要： PCT No. PCT/US97/22939 Sec. 371 Date Jun. 30, 1999 Sec. 102(e) Date Jun. 30, 1999 PCT Filed Dec. 5, 1997 PCT Pub. No. WO98/29486 PCT Pub. Date Jul. 9, 1998Disclosed are polymeric foam materials obtained using monomers based on silicon and/or germination. The copolymerization of silicon- or germanium-based monomers provide foams that have low glass transition temperatures and low densities. These foams also exhibit relatively high yield stress values, which make the foams suitable for absorption of fluids, particularly aqueous fluids such as urine and menses (when the foams are rendered hydrophilic). The foams have a variety of other uses, including insulation applications.

摘要： The present invention relates to compressable polymeric foam materials useful as insulation. These polymeric foams are prepared by polymerization of certain water-in-oil emulsions having a relatively high ratio of water phase to oil phase, commonly known as "HIPEs." The polymeric foam materials comprise a generally hydrophobic, flexible or semi-flexible, nonionic polymeric foam structure of interconnected open-cells. The foam structures have: (a) a specific surface area per foam volume of at least about 0.01 m2/cc; (b) an expanded density of less than about 0.05 g/cc; and (c) a ratio of expanded to compressed thickness of at least about 3:1; wherein when the foam is compressed to 33% of its original expanded thickness and is thereafter maintained without artificial restraint on its surface, said foam will reexpand by no more than 50% after 21 days at ambient temperature (22 DEG C.). In a preferred embodiment, the foams of the present invention, when heated to their Tg or higher, will reexpand to 90% of their original thickness within about 1 day or less. The invention also relates to a process for making the compressible polymeric foam material comprising polymerizing a water-in-oil emulsion having a volume to weight ratio of water phase to oil phase in the range of from about 20:1 to about 250:1.
