Abstract: The invention relates to foam composites having improved properties. 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 high internal phase emulsions, or nullHIPEs.null The HIPE-derived foam materials used in the present invention comprise a generally hydrophobic, flexible, semi-flexible, or rigid nonionic polymeric foam structure of interconnected open-cells. These foam structures have a density of less than about 100 mg/cc, a glass transition temperature (Tg) of between about null40null and 90null C., and at least about 1% by weight compatible fibers incorporated into the foam. The foam composites have improved tensile properties compared to foams having no incorporated fibers or foams having noncompatible fibers incorporated therein.

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.

Abstract: Stable high internal phase water-in-oil emulsions containing polymerizable vinyl monomers, crosslinking monomers and initiators are obtained, useful in producing low density porous crosslinked polymeric materials by using a surfactant system containing (a) an anionic surfactant, the anionic surfactant having an oil soluble tail and an anionic functional group and (b) one or more quatemary salts having one or more hydrocarbon groups having greater than or equal to 8 carbon atoms. A water-in-oil emulsion can be formed with lower surfactant concentration than sorbitan fatty acid ester alone and improved surfactant performance at elevated temperatures is obtained.

Abstract: The present invention relates to a HIPE-derived heterogeneous polymeric foam structure of interconnected open-cells, wherein the foam structure has at least two distinct regions. Such heterogeneous foams have various applications, such as energy and fluid absorption, insulation, and filtration. The invention further relates to a heterogeneous absorbent polymeric foam that, upon contact with aqueous fluids (in particular body fluids such as urine and blood), can acquire, distribute, and store these fluids. The foams of the invention have at least two distinct regions having different density, polymer composition, surface properties, and/or microcellular morphology. The invention further relates to a process for obtaining the heterogeneous foams by polymerizing a high internal phase water-in-oil emulsion, or HIPE. In one aspect, the process utilizes at least two distinct HIPEs, with each emulsion having a relatively small amount of an oil phase and a relatively greater amount of a water phase.
