Water-soluble polymers consist of (a) monoethylenically unsaturated dicarboxylic acids and/or their salts; (b) monoethylenically unsaturated monocarboxylic acids and/or their salts; (c) mono-unsaturated monomers that may be hydrolysed or saponified into monomers with a hydroxyl group covalently bound to the C-C chain; (d) monoethylenically unsaturated sulphonic acid or sulphate group containing monomers and optionally (e) other radically copolymerisable monomers, the sum of monomers (a) to (e) being equal to 100% by weight. Also disclosed is a process producing these polymers by radical polymerisation and hydrolysis in an aqueous medium, as well as the use of said polymers as additives or cobuilders in washing and cleaning agents, for the preliminary treatment of cotton, as bleach stabilisers, as textile printing auxiliary materials and for producing leathers, and also as water softeners, dispersants, and washing and cleaning agents.

Ces polymères solubles dans l'eau sont constitués de (a) acides dicarboxyliques monoéthyléniquement insaturés et/ou leurs sels; (b) acides monocarboxyliques monoéthyléniquement insaturés et/ou leurs sels; (c) monomères mono-insaturés susceptibles de se transformer par hydrolyse ou par saponification en monomères avec un groupe hydroxyle lié par covalence à la chaîne C-C; (d) monomères contenant des groupes sulfates ou acides sulfoniques monoéthyléniquement insaturés et le cas échéant (e) autres monomères radicalement copolymérisables, la somme des monomères (a) à (e) étant égale à 100 % en poids. L'invention concerne également un procédé de production de ces polymères par polymérisation radicale et hydrolyse dans un milieu aqueux, ainsi que l'utilisation de ces polymères comme adjuvants ou co-adjuvants dans des produits de lavage et de nettoyage, pour le pré-traitement du coton, comme stabilisateurs du blanchiment, comme substances auxiliaires pendant l'impression de matières textiles et lors de la production de cuirs, et comme adoucissants de l'eau, dispersants et agents de lavage et de nettoyage.
