摘要：
Graft copolymers obtainable by free radical-initiated copolymerization of(A) a monomer mixture comprising(a) a monoethylenically unsaturated C.sub.4 - to C.sub.8 -dicarboxylic acid, or an anhydride, alkali metal salt or ammonium salt thereof,(b) a monoethylenically unsaturated C.sub.3 - to C.sub.10 -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.
