International Classification:

C08J 928

US Classification:

521 64, 521 53, 521 54

Abstract:

Described are implements made from a durable HIPE foam material. The HIPE foam has a Toughness Index of at least 75 where the Toughness Index relates properties related to durability (e. g. , density, tan[ ] height, glass transition temperature, and abrasion resistance) into a single composite descriptor thereof.

International Classification:

C08J 928

US Classification:

264 464, 264 41, 2642971, 521 64

Abstract:

Described is a method of forming and curing high internal phase emulsions (HIPEs) into shaped three dimensional foam implements. In general the method uses the steps of: providing a HIPE, depositing the HIPE into a mold cavity having a predetermined three dimensional shape, curing the HIPE in the mold cavity to form a HIPE foam, and stripping the HIPE foam from the mold cavity to form the three dimensional foam implement. The molded implements are widely useful as components in absorbent articles, toys, insulation, and other uses where a combination of low density and tridimensional shape are desired.

US Classification:

604368, 604366, 604372, 604375, 604378

Abstract:

Absorbent members useful in the containment of body fluids such as urine, that have at least one region containing hydrogel-forming absorbent polymer in a concentration of from about 50 to 100% by weight and providing a gel-continuous fluid transportation zone when in a swollen state. This hydrogel-forming absorbent polymer has: (a) a Dynamic Gelling Rate of at least about 0. 18 g/g/sec; (b) a Performance under Pressure (PUP) capacity value of at least about 25 g/g under a confining pressure of 0. 7 psi (5 kPa); and (c) when the hydrogel-forming absorbent polymer is in the form of particles, a mass median particle size of at least about 100 m.

US Classification:

442/181000, 156/070000

Abstract:

The present invention relates to polymeric foam materials useful as insulation in clothing articles. 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 in the art as “HIPEs.” As used herein, polymeric foam materials which result from the polymerization of such emulsions are referred to hereafter as “HIPE foams.” These HPE foams comprise a generally hydrophobic, flexible or semi-flexible, nonionic polymeric foam structure of interconnected open-cells. The HIPE foams of the present invention have: (a) a specific surface area per foam volume of at least about 0.01 m/cc; (b) a density of less than about 0.0625 g/cc; and (c) a glass transition temperature (Tg) between about -40 C. and about 90 C.
