摘要： The invention relates to foams made from water-absorbing, basic polymers, which can be produced by: (I) foaming a cross-linkable aqueous mixture which contains (a) at least one basic polymer whose basic groups are optionally neutralized; (b) at least one cross-linking agent; (c) at least one surface active agent; (d) optionally at least one solubilizer; (e) optionally thickener, foam stabilizers, filling materials, fibers and/or cell nucleator and (f) optionally particle-shaped, water-absorbing acid polymers, wherein a gas that is inert to radicals is dissolved for foaming purposes in the cross-linkable, aqueous mixture at a pressure ranging from 2 to 400 bar, which is then relieved at atmospheric pressure or wherein foaming occurs by dispersing fine bubbles of a gas that is inert to radicals, and (II) crosslinking the foamed mixture by forming a foamy hydrogel and optionally regulating the water content of the foamy polymer to 1 to 60 percent by weight. The invention further relates to a method for the production of foams by implementing the above-mentioned measures (I and II) and to the utilization of the resulting foams in hygiene articles for the absorption of body fluids, in dressing materials to cover wounds, as sealing materials, packaging material, soil conditioners, soil substitutes, mud drainage, the absorption of acid aqueous wastes, for thickening aqueous paints in the disposal of paint residues, dehydrating water-containing oils or hydrocarbons or as material for filters in ventilation systems.

摘要： The invention relates to a method for determining the swelling behavior and the swelling kinetics of super absorbent materials (9) such as polymer gels, whereby a defined volume of dry super absorbent materials (9) is introduced into a measuring vessel (7), and a pressure force (12) is exerted onto the super absorbent material (9) by means of an element (4) that can be displaced inside the measuring vessel (7). The expansion of the super absorbent material (9) inside the chamber (14) is continuously detected by means of a non-contact detection of the change in height of a tube (4), which delimits the chamber (14), is guided inside a measuring vessel (7), and which is provided with a height marking (6).

摘要： The invention relates to the use of cross-linked polymers which have a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution) and which contain polymerised monoethylenic unsaturated monomers that contain acid groups and/or the alkali salts or ammonium salts thereof and optionally additional polymerised monoethylenic unsaturated monomers. Said cross-linked polymers are used as an additive for compact, particle-shaped washing and cleaning agents for increasing the disintegration rate when being brought into contact with water. The invention also relates to the use of compact, particle-shaped washing and cleaning agents which contain cross-linked polymers with a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution).

摘要： The invention relates to water-absorbing, cross-linked polymerizates which are in the form of a foam and which can be obtained by (I) foaming a polymerizable aqueous mixture which contains: (a) acid groups containing monoethylenically unsaturated monomers which are optionally neutralized; (b) optional other monoethylenically unsaturated monomers; (c) cross-linking agents; (d) initiators; (e) 0.1 to 20 wt. % of at least one surface active agent; (f) optionally at least one dissolving mediator; and (g) optional thickeners, foam stabilizers, polymerization chain transfer agents, fillers and/or cell nucleating agents. Fine bubbles of a gas which is inert against radicals causes foaming by dispersion in the polymerizable aqueous mixture. The inventive polymerizates can also be obtained by (II) polymerizing the foamed mixture by forming a hydrogel which is in the form of a foam, whereby at least 20 mol % of the monomers (a) containing acid groups are neutralized with tertiary alkanolamines and/or the free acid groups of the hydrogel in the form of a foam are neutralized with at least one alkanolamine to at least 20 mol % after the polymerization, and the water content of the polymerizate which is in the form of a foam is set at 1 to 60 wt. %. The invention additionally relates to a method for producing the inventive polymerizates and to the utilization thereof in sanitary articles which are used for absorbing body fluids and in bandaging material used for covering wounds.
