    Abstract: 2118308 9323377 PCTABS00028 A process is disclosed for preparing N-allyl compounds having general formula (I), in which (II) stands for a N-containing aromatic heterocycle; R1, R3 and R4 represent independently from each other hydrogen or C1-C4-alkyl; R2 stands for hydrogen or methyl; n equals 1, 2, 3 or 4 and X- is an anion for rendering water-soluble. The process is characterized in that compounds having formula (II) are reacted in an aqueous medium with compounds having formula (III), in which A stands for a residue which can be split as an anion. These compounds are very suitable as brighteners for nickel-plating.

    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.
