Abstract: Polyaminoamides in which at least some of the amine nitrogen atoms have been alkoxylated, amidated, or alkylated are suitable for hydrophilicizing surfaces, in particular of linear or sheet-like textile structures made from synthetic fibers, or structures in the form of their plastics film or of a plastics molding. The hydrophilicized linear or sheet-like textile structures are particularly used in hygiene items.

Abstract: Solid dosage forms are obtained by mixing at least one polymeric binder, at least one active ingredient, and, where appropriate, conventional additives to form a plastic mixture, and shaping, using as polymeric binder a copolymer of an N-vinyllactam and a copolymerizable monomer having a hydrophobic radical. Dosage forms which show slow release of the active ingredient are obtained in a simple and low-cost manner.
