    摘要： The present invention relates to a particulate, linear, sheet-like or three-dimensional structure comprising, at least on its surface, a hydrophilicizing amount of at least one acylated polyamine, where at least some of the polyamine nitrogen atoms bear acyl radicals of the formula I R1—CO—  (I) where R1 is hydrogen, C1–C27-alkyl, C7–C27-alkenyl or C6–C10-aryl, and where the alkyl, alkenyl and aryl groups may bear at least one substituent selected from the class consisting of hydroxyl, alkoxy, alkoxycarbonyl and NE1E2, where E1 and E2 may be identical or different and are hydrogen, alkyl or acyl, to the use of acylated polyamines for modifying the surface properties of solids, and also to a process for modifying the surface properties of particulate, linear, sheet-like, or three-dimensional structures.

    摘要： Hydrophilic open-celled resilient foams containing melamine-formaldehyde resins, characterized by a droplet absorption rate of less than 5 seconds and an EU standard EN ISO 14184-1 formaldehyde emission of less than 100 mg of formaldehyde/kg of foam, and obtainable by (a) heating an aqueous solution or dispersion each containing at least a melamine-formaldehyde precondensate, an emulsifier, a blowing agent and a curing agent to form a foam and crosslink the precondensate, (b) then conditioning the foam at from 120 to 300° C. for from 1 to 180 minutes to remove volatiles, and (c) treating the foam during the conditioning or thereafter with at least one hydrophilicizer and/or with ozone, a corona discharge or a plasma, are useful in hygiene articles to acquire, distribute and immobilize body fluids.
