    Abstract: Polymers containing acid groups are modified by reaction of(a) polymers which comprise at least 5% by weight of a copolymerized monoethylenically unsaturated monomer containing acid groups, have molar masses of from 200 to 100,000 and are obtainable by free-radical polymerization of monoethylenically unsaturated acids in aqueous solution in the presence or absence of other monoethylenically unsaturated monomers and in the presence of at least 4% by weight, based on the monomers used in the polymerization, of a water-soluble sulfur compound in which the sulfur is in the oxidation state +4,with(b) polyalkylene glycols which are end-capped at one end, alkylpolyalkylene glycol amines or mixtures thereof, or mixtures of at least one of the two compounds specified with up to 30% by weight, based on the mixtures, of ammonia, amines, alcohols, hydroxycarboxylic acids or aminocarboxylic acidsat up to 250° C.

    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.
