Abstract: Graft copolymers obtainable by free radical-initiated copolymerization of (A) a monomer mixture comprising (a) a monoethylenically unsaturated C4- to C8-dicarboxylic acid, or an anhydride, alkali metal salt or ammonium salt thereof, (b) a monoethylenically unsaturated C3- to C10-carboxylic acid, or an alkali metal salt or ammonium salt thereof, (c) if desired another monoethylenically unsaturated monomer which can be copolymerized with monomer (a) and (b), and (d) a monomer containing two or more ethylenically unsaturated, non-conjugated double bonds in the molecule, in the presence of (B) a monosaccharide, oligosaccharide, polysaccharide, oxidatively, hydrolytically or enzymatically degraded polysaccharide, oxidized, hydrolytically or enzymatically degraded polysaccharide, or chemically modified monosaccharide, oligosaccharide or polysaccharide, in the weight ratio (A):(B) of (95 to 20):(5 to 80), a process for the preparation of the graft copolymers, and detergents and cleaners containing the graft copolymers in amounts of from 0.1 to 20% by weight, are described.
