Abstract: The invention relates to the use of cross-linked polymers which have a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution) and which contain polymerised monoethylenic unsaturated monomers that contain acid groups and/or the alkali salts or ammonium salts thereof and optionally additional polymerised monoethylenic unsaturated monomers. Said cross-linked polymers are used as an additive for compact, particle-shaped washing and cleaning agents for increasing the disintegration rate when being brought into contact with water. The invention also relates to the use of compact, particle-shaped washing and cleaning agents which contain cross-linked polymers with a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution).

Abstract: The use is disclosed of a compound having the general formula (I), as well as its alkali salts, as scaling inhibitors and/or (co)-builders. In the formula (I), R' stands for hydrogen and R and R' independently represent branched or non-branched aliphatic C4-28 radicals which can contain one or several double C-C and/or triple C-C bonds. Radicals R and R' may be interrupted by one or more non-adjacent oxygen atoms, NH groups and/or N-C1-4-alkyl groups, and may be substituted by one or more hydroxyl groups, primary amino groups and/or secondary C1-4-alkylamino groups; or radicals R and R' are hydrogen atoms and radical R' has the above-mentioned meaning; or R' has the meaning given above for R' and R and R' are hydrogen atoms.

Abstract: The invention relates to a process for preparing copolymers from vinyl esters and monoethylenically unsaturated carboxylic acids by the radical copolymerisation of: (a) 20 to 80 mol % vinyl esters of aliphatic monocarboxylic acids having at least two carbon atoms, (b) 80 to 20 mol % monoethylenically unsaturated carboxylic acids and, optionally, (c) 0 to 30 mol % of other monoethylenically unsaturated monomers which can be copolymerised, and/or (d) 0 to 10 mol % monomers containing at least two ethylenically unsaturated non-conjugated double bonds in the molecule, in the presence of at least one sulphur, phosphorus and/or nitrogen compound having a reducing effect and of 0.05 to 30 wt %, relative to the monomers, of at least one surfactant in an aqueous medium and in the presence of initiators and, optionally, regulators. The invention further relates to the use of the copolymers or the copolymers comprising vinyl alcohol units obtained therefrom by hydrolysis and/or oxidation, as additives for washing and cleaning agents.
