Abstract of the Disclosure Mixtures of (I) polymers of monoethylenically unsaturated dicarboxylic acids having a molecular weight of from 200 to 5,000 and (II) (1) copolymers having a molecular weight of from 10,000 to 150,000 and comprising (a) from 10 to 70% by weight of monoethylenically unsaturated C4-C8-dicarboxylic acids or the salts thereof and (b) from 30 to 90% by weight of monoethylenically unsaturated C3-C10-monocarboxylic acids and/or the salts thereof, (2) homo- and copolymers, each having a molecular weight of from 1,000 to 500,000 and obtained from mono- ethylenically unsaturated C3-C10-monocarboxylic acids, (3) graft polymers having a molecular weight of from 5,000 to 150,000, which are obtainable by free radical graft polymerization of (A) monoethylenically unsaturated C3-C10-carboxylic acids or the anhydrides and/or the salts thereof in the presence of (B) mono-, oligo- or polysaccharides and the derivatives thereof in a weight ratio (A) (B) of (95 to 20) (5 to 80), and/or (4) polyaminocarboxylic acids and/or polymers containing aminocarboxylic acid groups contain the components (I) and (II) in a weight ratio of from 10 : 0.5 to 0.5 : 10 and are used as additives for phosphate-free or low-phosphate textile detergents or as dispersants or coating inhibitors in cleaners for hard surfaces.
