Abstract: The invention concerns the use of aqueous polymer dispersions for protecting metallic surfaces against corrosion. The aqueous polymer dispersions are based on copolymers of C2-C14 olefins and monomers which contain or can form by hydrolysis acid functional groups and which in addition also contain dyes and/or corrosion inhibitors dissolved or dispersed in the polymer phase.

Abstract: 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.
