Method for the production of composite materials

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 an elastic silicate foam by foaming a mixture comprising

Elastic inorganic-organic hybrid foam

Foams composed of water-absorbing basic polymers, obtainable by (I) foaming a crosslinkable aqueous mixture including (a) at least one basic polymer whose basic groups have optionally been neutralized, (b) at least one crosslinker, (c) at least one surfactant, (d) optionally at least one solubilizer, (e) optionally thickeners, foam stabilizers, fillers, fibers and/or cell nucleators, and (f) optionally particulate water-absorbing acidic polymers, by dissolving a gas which is inert toward free radicals in the crosslinkable aqueous mixture under a pressure from 2 to 400 bar and subsequently decompressing the crosslinkable aqueous mixture to atmospheric or by dispersing fine bubbles of a gas which is inert toward free radicals, and (II) crosslinking the foamed mixture to form a hydrogel foam and if applicable adjusting the water content of the polymer foam to 1-60% by weight. Preparation of the foams by application of the abovementioned measures (I) and (II) and use of the thus obtainable foams 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 absorb aqueous acidic wastes, 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.

Foams made from water-absorbing, basic polymers, method for the production and utilization thereof

A process for the reduction of the residual monomer content and enhancement of the wet strength of articles formed from water absorbent crosslinked polymer foams containing units derived from monoethylenically unsaturated acids, which comprises treating the formed articles with at least 0.5% by weight of a polymer containing primary and/or secondary amino groups and having a molar mass of at least 300, the formed foam articles thus obtainable and use of the wet strength enhanced formed foam articles in hygiene articles.

Process for the reduction of the residual monomer content of water-absorbent foam

Disclosed is a method for determining the swellability and the swelling kinetics of superabsorbent material () such as polymer gels, for example, which comprises introducing a defined volume of the dry superabsorbent material () into a measuring vessel (), using a movable element () within said measuring vessel () to apply a restraining force () to said superabsorbent material () and capturing the expansion of said superabsorbent material () contactlessly within a chamber () in a continuous manner by capturing the change in height of a piston () which bounds said chamber (), travels in a measuring vessel () and is marked with a height scale ().
