WATER-SOLUBLE COPOLYMERS, PROCESS FOR PRODUCING THE SAME AND THEIR USE

摘要

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.
