  • Publication number: 20020132106
    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 “HIPEs.” 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 −40° and 90° 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.

  • Publication number: 20020123283
    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.

    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 &mgr;m.

  • Patent number: 6406648
    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.

  • Patent number: 6376565
    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[&dgr;] height, glass transition temperature, and abrasion resistance) into a single composite descriptor thereof. Exemplary implements include: wipes, toys, stamps, art media, targets, food preparation implements, plant care implements, and medical wraps.

  • Patent number: 6232520
    Abstract: Disclosed in the present application are absorbent polymer compositions useful in the absorption of body fluids such as urine, menses and the like. In particular, the invention relates to mixed-bed ion-exchange absorbent polymer compositions having excellent absorbency performance properties in terms of absorbent capacity under a confining pressure of 0.7 psi and/or 1.4 psi. Certain mixed-bed ion-exchange absorbent polymer compositions of the present invention have excellent absorbency properties not only for a synthetic urine with a composition and ionic strength that is typical of young infants but also for a high ionic strength synthetic urine that has a composition and ionic strength that is typical of the urine of older infants and toddlers. The invention also relates to absorbent members comprising the mixed-bed ion-exchange absorbent polymer compositions, and absorbent articles comprising the absorbent members.
