Abstract: Water-absorbing foamlike crosslinked polymers which are obtainable by(I) foaming a polymerizable aqueous mixture which consists of(a) monoethylenically unsaturated monomers containing acid groups, which are at least 50 mol % neutralized,(b) with or without other monoethylenically unsaturated monomers,(c) crosslinker,(d) initiators,(e) from 0.1 to 20% by weight of at least one surfactant,(f) with or without one or more solubilizers and(g) with or without thickeners, foam stabilizers, polymerization regulators, fillers and/or cell nucleating agents,the foaming being performed by dispersing fine bubbles of a gas inert to free radicals, and(II) polymerizing the foamed mixture with formation of a foamed hydrogel, with or without adjusting the water content of the foamed polymer to from 1 to 60% by weight, processes for their preparation and their use in sanitary articles which are used for absorbing body fluids and in dressing materials for covering wounds are described.

Abstract: The invention relates to secondary C10 to C18 surfactant alcohols of the general formula (I), wherein R represents methyl or ethyl and R' represents a linear or branched alkyl group with 6-13 C atoms, excepting 5-ethyl-2-nonanol and 6-ethyl-3-decanol, in addition to fatty alcohol alkoxylates, alkyl phosphates, alkyl sulphates, alkyl ether phosphates and alkyl ether sulphates. The secondary C10 to C18 surfactant alcohols can be produced by a simple aldol condensation of linear or branched saturated or unsaturated C7-C14 aldehydes, excepting 2-ethyl hexanal, with acetone or methyl ethyl ketone and the subsequent hydrogenation of the condensation product. In the preferred method, the aldol condensation is heterogenically catalysed under hydrogenation conditions and the saturated ketone that has been formed is subsequently hydrogenated.

Abstract: A process for the production of polymers with peroxycarboxyl groups (I), in which a suspension of polymer containing mono-unsaturated dicarboxylic acid anhydride units (II) in an inert diluent is mixed with hydrogen peroxide (HPO). Also claimed are copolymers (II) containing unsaturated anhydride(s) and N-vinyl-lactam(s) as base units.
