Thermoplastic heteropolysaccharide derivatives, articles employing such thermoplastic heteropolysaccharide derivatives and methods for making such thermoplastic heteropolysaccharide derivatives are provided.

Thermoplastic heteropolysaccharide derivatives and methods for making same

The present invention relates to cationic polymers, such as polyaminoamide epichlorohydrin (PAE), that are derived from renewable resources and can be used to produce wet strength resins suitable for a variety of applications, such as in absorbent paper articles.

Wet strength resins derived from renewable resources

This application relates to flexible, microporous, open-celled polymeric foam materials with physical characteristics that make them suitable for a variety of uses. This application particularly relates to methods particularly suitable for continuously curing high internal phase emulsions to form such foams.

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.

Absorbent members for body fluids using hydrogel-forming absorbent polymer

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.

Method of making shaped foam implements

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&lsqb;&dgr;&rsqb; 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.

Implements comprising highly durable foam materials derived from high internal phase emulsions

This application relates to flexible, microporous, open-celled polymeric foam materials with physical characteristics that make them suitable for a variety of uses. This application particularly relates to monomer compositions having short curing times for preparing such foam materials from high internal phase emulsions.

Rapid preparation of foam materials from high internal phase emulsions

This application relates to flexible, microporous, open-celled polymeric foam materials with physical characteristics that make them suitble for a variety of uses. This application particularly relates to degassing the components of the high internal phase emulsions which are subsequently cured to form such foams.

Method for degassification of high internal phase emulsion components

Disclosed are protective, flexible mats for absorbing liquids on floors and other surfaces which contain a waterproof component and a polymeric foam sheet formed by polymerizing a high internal phase water-in-oil emulsion. The mats can also contain a non-skid material and/or at least one liquid pervious sheet. The mats are suitable for absorbing hydrophilic and hydrophobic liquids.

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.

Biodegradable and/or compostable polymers are made from isoprene, 2,3-dimethyl-1,3-butadiene or like conjugated dienes and a crosslinking agent having a cleavable linking group such as ethylene glycol dimethacrylate. These polymers can be used to make absorbent foams that are useful in absorbent articles such as diapers, as well as other biodegradable articles such as films, and latexes useful as binders and adhesives.

This application relates to flexible, microporous, open-celled polymeric foam materials with physical characteristics that make them suitable for a variety of uses. This application particularly relates to high temperature processes having short curing times for preparing such foam materials from high internal phase emulsions.

Processes for the rapid preparation of foam materials from high internal phase emulsions at high temperatures and pressures

Disclosed are microporous, open-celled polymeric foams formed by polymerizing a high internal phase water-in-oil emulsion comprising a continuous oil phase and discontinuous water phase where the foam has a Limiting Oxygen Index (LOI) value of at least about 18% Such foams are commonly known in the art as 'HIPEs'. The foams have a variety of flame retardant applications, including use in insulation.
