摘要:
The present invention relates to layered bodies consisting of at least one plastic foam and/or latex foam layer and particulate, superabsorbent polymers for the absorption of water and aqueous liquids, which bodies comprise the superabsorber on, between, or below the foamed plastic and/or latex layer in a quantitatively and/or locally predetermined and fixed area, configuration at a quantity ratio of plastic and/or latex foam to the superabsorber of 1:500 to 50:1. The plastic/latex foam may comprise fillers, pigments and/or synthetic fibers. The layered bodies have an increased absorption capacity for water and aqueous liquids, in particular under load. They are manufactured by spreading out the foam, applying the superabsorber in the predetermined quantity ratio, optionally by using a stencil, and by fixing it by means of a heat treatment. These layered bodies are used in hygienic articles, as components in natural or artificial soils, as insulating material for pipes and ducts, primarily for cables and constructional elements, as liquid-absorbing and liquid-storing component in packaging materials, and as a part in garments.

The present invention relates to a process for the preparation of water-absorbent, foam-type polymer structures, wherein an aqueous composition is foamed, and the foamed aqueous composition is then heated at a temperature in a range of from 50 to 300° C., so that the polymer crosslinks at least partially and the content of water is adjusted to not more than 15 wt. %, based on the total weight of the foam-type polymer structure that forms.

摘要:
A polymer composition, a process for the production of a polymer composition, in particular of an absorbent, are disclosed which substantially consist of a special component A based on renewable polysaccharide raw materials, a special component B consisting of a water-soluble polymer, a matrix material, an ionic and/or covalent cross-linking agent, or an anti-blocking agent, which is obtainable in that the water-swellable polymer is brought together with the polysaccharide polymer, that these are dried and ground then, the other components are added, and mixing up to homogeneity is effected followed by a heat treatment, and that during the addition of the cross-linking agent, after said heat treatment, the same is optionally fixed by the matrix by means of a final heat treatment. Additionally the use of this polymer composition and (animal) hygiene items and chemico-technical products are disclosed which comprise a previously manufactured polymer composition.

A polymer composition, in particular an absorbent composition or an active substance-containing depot material are disclosed which substantially consist of a water-soluble and/or water-swellable polymer based on polysaccharides as the main component, and of a water-swellable polymer as further component, used as polymeric components, and of a matrix material for the prevention of separation and gel blocking, an ionic or covalent cross-linking agent, a reactive additive, as well as of an anti-blocking agent. Additionally, their production and use as well as (animal) hygiene items and chemico-technical products are disclosed which comprise these polymer compositions or absorbent compositions.
