Abstract: The invention relates to a cleaning agent composition comprising at least one surface-active agent, at least one builder and at least one polymer containing nitrogen. The nitrogen-containing polymer is, for example, an alkoxylated polyvinylamine, an alkoxylated, acylated or alkylated polyaminoamide or a polyurethane urea with tertiary amino groups. The nitrogen-containing polymers facilitate the solution of dirt.

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.

Abstract: Aqueous copolymer dispersions are obtained by copolymerization of (A) hydrophilic N-vinyl monomers with a maximum polymerisation rate (MPR) above pH 7 and (B) hydrophobic mono-unsaturated monomers with an MPR below pH 7 in presence of radical starters and with the pH controlled to fall by 2-5 units from start to finish. A process for the production of aqueous copolymer dispersions by radical polymerisation in an aqueous medium containing 10-90 wt% hydrophilic monomer(s) (A) with an N-vinyl group, showing an MPR at pH values above 7, 10-90 wt% mono-unsaturated hydrophobic monomer(s) (B) showing an MPR at pH values below 7 and 0.01-20 wt% water-soluble and/or -insoluble radical starter(s). In this process the pH is controlled during polymerisation so that it decreases by 2-5 units between the beginning and end of the reaction. An Independent claim is also included for aqueous copolymer dispersions obtained by this process and copolymers obtained by drying the dispersions.

Abstract: The invention relates to a method for producing solid dosing forms by mixing at least one polymeric binding agent, at least one active substance, and optional common additives while producing a plastic mixture and during shaping, whereby a copolymer from a N-vinyl lactam and from an copolymerizable monomer with a hydrophobic radical is used as a polymeric binding agent. Dosing forms which slowly release the active substance are obtained in a simple and economical manner.

Abstract: Polyamine amides whose amino nitrogen atoms are at least partially alkoxylated, amidated or alkylated are suitable for hydrophilizing surfaces, especially of two- or three-dimensional textile structures from plastic fibers or structures in the form of a plastic film or a molded plastic body. The hydrophilized two- or three-dimensional textile structures are especially used in sanitary products.
