The present invention relates to water-soluble polymers built up of a) monoethylenically unsaturated dicarboxylic acids and/or their salts, b) monoethylenically unsaturated monocarboxylic acids and/or their salts, c) monounsaturated monomers which, after hydrolysis or saponification, can be converted into monomers having a hydroxyl group covalently bonded at the C—C-chain, d) monoethylenically unsaturated sulfonic acid groups or sulfate groups-containing monomers, and optionally e) further radically copolymerizable monomers, with the sum of the monomers of a) to e) amounting to 100%. The present invention further relates to a process for the production of these polymers by radical polymerization and hydrolysis in aqueous medium, and to the use of these polymers as additive or cobuilder in detergents and cleaners, in the pretreatment of cotton, as bleaching stabilizers, as auxiliary agent in textile printing, and in the manufacture of leather, as well as for the inhibition of water hardness, and as dispersing agent as well as detergents and cleaners.
A water-soluble copolymer comprising a —C—C— backbone and at least one hydroxyl group covalently bonded to the backbone, wherein the copolymer is comprised of the following monomers radically copolymerized in a first aqueous medium:
