Use in hygiene articles of articles formed of water-absorbent, predominantly open-celled crosslinked acid-functional addition polymer foams Abstract The use of articles formed of water-absorbent open-celled crosslinked acid-functional addition polymer foams and containing finely divided silicon dioxide and/or at least one surfactant on their surface as an acquisition and/or distribution layer in hygiene articles.

Use of water-absorbent, predominantly open-celled crosslinked acid-functional addition polymer foams in hygiene articles

A process for producing thin absorbent planar structures which may be used in hygiene products such as diapers, incontinence products, wound contact materials or sanitary napkins to absorb body fluids, comprises the steps of:

Method using a dry fluidized bed for producing thin, absorbent surface structures

Superabsorbent foam comprising superabsorbent fiber and/or fruit fiber, processes for producing superabsorbent foam having improved wet strength by foaming a crosslinkable aqueous mixture comprising at least 50 mol % neutralized acid-functional monoethylenically unsaturated monomer or at least one basic polymer, crosslinker, superabsorbent synthetic fiber and/or fruit fiber and at least one surfactant and subsequently polymerizing the monomer in the foamed mixture or crosslinking the basic polymer to form a hydrogel foam and use of the thus obtainable foam in hygiene articles to absorb body fluids, in dressing material to cover wounds, as a sealing material, as a packaging material, as a soil improver, as a soil substitute, to dewater sludges, to thicken waterborne paints or coatings in the course of disposing of residual quantities thereof, to dewater water-containing oils or hydrocarbons or as a material for filters in ventilation systems.

Superabsorbent foam, method for the production thereof, and use thereof

The present invention relates to novel hydrophilic swellable addition polymers comprising improved odor control, a process for their preparation and their use for absorbing aqueous fluids and a process for screening superabsorbents.

Acidic superabsorbent hydrogels

Method using a dry fluidised bed for producing thin, absorbent surface structures

The present invention relates to polymer mixtures comprising hydrogel forming polymers capable of absorbing aqueous fluids, having different pH values and each being preparable by polymerization of olefinically unsaturated carboxylic acids or derivatives thereof, their preparation, use and hygiene articles containing same. More particularly, the invention relates to 2-component polymer mixtures comprising polymers having a pH range from acidic to neutral.

Polymer mixture of hydrogels with different pH value

The present invention relates to polymer mixtures including hydrogel-forming polymers capable of absorbing aqueous fluids and prepared by polymerization of olefinically unsaturated carboxylic acids or derivatives thereof together with copolymers of C&#x2013;Colefins or styrenes with anhydrides and also their preparation, use and hygiene articles which include same.

Polymer mixtures with improved odor control

Hydrophilic hydrogels with a high swelling capacity and method for producing and using them

Crosslinked, hydrophilic, highly swellable hydrogels, production thereof and use thereof
