The use is disclosed of graft polymers obtainable by radically-initiated polymerisation of (A) monomer mixtures comprising (a) 90-100 wt. % monoethylenically unsaturated C4-C8 dicarboxylic acids, their anhydrides or alkali- and/or ammonium salts; (b) 0-10 wt. % other monoethylenically unsaturated monomers which can be co-polymerised with monomers (a); and (c) 0-5 wt. % of at least two ethylenically unsaturated monomers with double bonds in the molecule, in the presence of (B) hydrogenated monosaccharides, hydrogenated oligosaccharides and/or hydrogenated polysaccharides, in relative weight proportions of (A):(B) of (95-20):(5-80). The graft polymers are proposed as additives to phosphate-free and phosphate-reduced washing and cleaning agents. Also disclosed are washing and cleaning agents containing the proposed graft copolymers in quantities of 0.1 to 20 wt. %. |
