A cleaner composition which comprises at least one surfactant, at least one builder and at least one nitrogen-containing polymer is described. 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 soil release.

Cleaning agent composition comprising polymers containing nitrogen

A polyurethane which contains, as incorporated units,

Polyurethane and the use thereof for modifying rheological properties

Compositions comprising at least one water-insoluble ingredient and at least one copolymer of

Compositions comprising copolymers of N-vinylcarboxamides and monomers with a hydrophobic radical, and use of these copolymers

Incorporation of crosslinked polyvinylpyrrolidone in a specific particle composition as a disintegrant in compact particulate laundry detergents or cleaning products, such a particle composition and the compact particulate laundry detergents themselves, a process for preparing such a compact particulate laundry detergents or cleaning products, and a process for preparing specific particle compositions.

Use of cross-linked polyvinylpyrrolidone as a disintegrant in compact, particulate detergents and cleaning agents

The use is described of particulate, water-insoluble and scarcely swellable polymers of ethylenically unsaturated monomers, which polymers contain, copolymerized, at least 20% by weight, based on the total weight of the monomers, of at least one &agr;,&bgr;-monoethylenically unsaturated monocarboxylic acid having from 3 to 6 carbons as filter aid for filtering aqueous liquids. Subject-matter of the invention are also water-insoluble, scarcely swellable polymers (popcorn polymers) that contain, copolymerized, &agr;,&bgr;-monoethylenically unsaturated carboxylic acids and styrene or styrene derivatives, and also a process for their preparation.

Particulate polymers as filter aids

The particle size of popcorn polymers is established during the popcorn polymerization by a process in which reaction mixtures forming popcorn polymers and comprising monoethylenically unsaturated monomers and a crosslinking agent are polymerized in the absence of oxygen and polymerization initiators at up to 200&deg; C. and in which the popcorn polymerization is carried out as a precipitation polymerization in water or in the absence of a solvent and the particle size of the popcorn polymers is controlled in the range from 1 &mgr;m to 10 mm by passing an inert gas stream into the reaction mixture, and popcorn polymers having a mean particle diameter of from >400 &mgr;m to 1500 &mgr;m are used as beverage clarifiers, antidiarrheal drugs and disintegration accelerators for tablets.

Method for adjusting the particle size of popcorn polymers during popcorn polymerization

Process for preparing aqueous dispersions of copolymers from hydrophilic and hydrophilic monomers, copolymers obtainable therefrom and uses thereof

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.

Method for producing solid dosing forms

Styrene-containing popcorn polymers, method for producing same and utilisation
