ABSTRACT:
The present invention relates to water-soluble, acid-groups-containing graft copolymers which are at least partially biodegradable and are based on sugars and monoethylenically unsaturated carboxylic acids, sulfonic acids and/or phosphonic acids or the salts of said acids as well as optional further monomers. The present invention further relates to a process for producing the graft copolymers at temperatures of up to 200.degree. C. by means of-radical polymerization initiators, in that a total mixture of 5-60%-wt. mono-, di- and oligosaccharides, the derivatives thereof or the mixtures thereof, and 95-40%-wt. of a monomer mixture comprising at least one monoethylenically unsaturated carboxylic acid, at least one monoethylenically unsaturated sulfonic acid, one monoethylenically unsaturated sulfuric acid ester and/or vinylphosphonic acid or the salts of said acids with monovalent cations, as well as optional further monomers is polymerized. The present invention further relates to the use of the graft copolymers in aqueous systems, for binding multivalent metal ions, inhibiting the water hardness, as additive in detergents and cleaning agents, as textile auxiliary, dispersing agent, in particular for pigments, and as auxiliary agent in the production of paper and leather.
