A water-soluble or water-dispersible graft copolymer obtainable by free-radical graft copolymerization of (I) at least one monoethylenically unsaturated monomer onto (II)polymers with a molecular weight of 200 - 5000 of mono- ethylenically unsaturated dicarboxylic acids or anhydrides thereof using from 5 to 2,000 parts by weight of the monomers (I) per 100 parts by weight of grafting base, a process for preparing the graft copolymers and the use of the graft copolymers as additive to phosphate-free or reduced phosphate textile detergents, as dispersants and preventers of deposits in cleaners for hard sur- faces and as water-treatment agents for reducing the deposition of scale and the separation out of water hardness in water-con- veying systems.
