    Abstract: PROBLEM TO BE SOLVED: To use a crosslinked polyvinylpyrrolidone so as to increase the disintegration rate of a compact granulated detergent and cleanser when contacted with water, by utilizing crosslinked polyvinylpyrrolidone particles each with a specific diameter. SOLUTION: Crosslinked polyvinylpyrrolidone particles each with a diameter of 50-400 μm, preferably 80-300 μm are used as an additive so as to increase the disintegration rate of a compact granulated detergent and cleanser when contacted with water. The compact granulated detergent and cleanser mean particles exhibiting detergent and cleanser activities, especially pellets, e.g. (dishwasher) detergent pellets, bleaching agent pellets, or detergent pellets for clothing especially for domestic use, more especially in a washer. It is desirable that at least 10 wt.%, preferably 15 wt.%, more preferably 25 wt.% of the crosslinked polyvinylpyrrolidone particles have each a diameter of

    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: Multifunctional polymers containing polymerized units of (a) alpha-Acyloxyacrylonitrile, alpha-haloacrylic acid, alpha-acyloxyacrylic ester and/or alpha-hydroxyacrylic acid, (b) monoethylenically unsaturated carboxylic acids, (c) vinyl esters of saturated aliphatic monocarboxylic acids and/or vinyl alcohol and optionally (d) other monoethylenically unsaturated monomers copolymerizable with said monomers (a) to (c) and optionally (e) crosslinkers containing at least two ethylenically unsaturated double bonds and having a K value of at least 7 (determined after H. Fikentscher in acetone at 25° C. and a polymer concentration of 1% by weight), processes for preparing multifunctional polymers by copolymerizing monomer mixtures of (a) alpha-acyloxyacrylonitrile, alpha-haloacrylic acid and/or alpha-acyloxyacrylic ester, (b) monoethylenically unsaturated carboxylic acids, (c) vinyl esters of saturated aliphatic monocarboxylic acids and optionally (d) other monoethylenically unsaturated monomers copolymerizable with said monomers (a) to (c) and optionally (e) crosslinkers containing at least two ethylenically unsaturated double bonds in the presence of polymerization initiators that form free radicals and partially or completely hydrolyzing the polymerized monomer units (a) and (c) in the copolymers thus obtainable and use of the multifunctional polymers in laundry detergents and cleaners, to bind polyvalent metal ions, as a stabilizer in textile bleaching and the bleaching of pulp for papermaking.
