Abstract:
PCT No. PCT/EP94/04187 Sec. 371 Date Feb. 28, 1995 Sec. 102(e) Date Feb. 28, 1995 PCT Filed Dec. 16, 1994 PCT Pub. No. WO95/17444 PCT Pub. Date Jun. 29, 1995The present invention relates to water-soluble, acid groups-containing graft copolymers which are at least partially biodegradable and are based on polyhydroxy compounds 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 said graft copolymers at temperatures of up to 200 DEG C. by means of radical polymerization initiators, in that a total mixture is polymerized which consists of 1-60%-wt. of polyhydroxy compounds, their derivatives or their mixtures, 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. 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.
