摘要

PCT No. PCT/EP96/00621 Sec. 371 Date Dec. 22, 1997 Sec. 102(e) Date Dec. 22, 1997 PCT Filed Feb. 14, 1996 PCT Pub. No. WO96/25959 PCT Pub. Date Aug. 29, 1996The invention relates to sheet-like absorbents for water and aqueous solutions, containing at a defined distribution A) at least one water-swellable synthetic and/or natural superabsorbent polymer, and B) at least one water-soluble synthetic and/or natural polymer as a matrix of sheet-like design wherein the superabsorbent component A) is integrated or fixed. The sheet-like absorbents have an increased absorptive capacity for water and aqueous liquids, particularly under load. They are manufactured by forming a sheet-like matrix from the water-soluble synthetic and/or natural polymers B) and providing same with said water-swellable synthetic and/or natural superabsorber A), e.g., by applying a solution of matrix B) on a surface, sprinkling same with component A), and drying the sheet-like structure thus obtained. Such sheet-like absorbents are used in hygienic articles, as components in natural or artificial soils, as insulating material for pipes and lines, primarily cables and building constructions, as liquid-absorbing and liquid-storing component in packaging materials, as a part in articles of clothing, and as a depot for the controlled release of an active substance.
