Abstract:
PCT No. PCT/EP96/00620 Sec. 371 Date Oct. 2, 1997 Sec. 102(e) Date Oct. 2, 1997 PCT Filed Feb. 14, 1996 PCT Pub. No. WO96/25958 PCT Pub. Date Aug. 29, 1996The invention relates to layered bodies for absorbing water and aqueous liquids, consisting of at least one water-soluble polymer foam layer and particulate superabsorbent polymerizates, which contain the superabsorber on top of, between or underneath the foamed polymer layer in a quantitatively and/or locally predetermined and fixed sheet-like arrangement at a quantity ratio of polymer foam and superabsorber of from 1:500 to 50:1. The polymer foam may contain fillers, pigments and/or synthetic fibers. The layered bodies have increased absorptive capacity for water and aqueous liquids, particularly under load. They are produced by spreading the foam in a sheet-like fashion, applying the superabsorber at the predetermined quantity ratio, optionally using a template, and fixing it by a heat treatment. Such layered bodies are used in hygiene articles, as components in natural or artificial soils, as insulating material for pipes and lines, particularly cables, and building constructions, as liquid-absorbing and storing component in packaging materials, and as a part in clothing articles.
