    Abstract: Use of graft copolymers obtained by: a) grafting alkylene glycols, polyalkylene glycols with molar masses up to 50,000, polytetrahydrofuran, glycerin, polyglycerin, addition products of alkylene oxides with 2 to 4 carbon atoms on mono- or polyvalent C1-C6 alcohols, as well as chain-lengthened reaction products of the above-mentioned compounds with polyvalent carboxylic acids or polyvalent isocyanates with: b) monoethylenically unsaturated C3-C8 carboxylic acids and possibly: c) other monoethylenically unsaturated compounds at temperatures of 40 to 100 DEG C in the presence of radical-forming initiators, as additives in phosphate-free or low-phosphate washing and cleaning products. The invention relates also to washing and cleaning products containing 0.1 to 15 wt. % of the above-mentioned graft polymerizates.

    Abstract: The use of copolymers which contain as essential copolymerised units (a) 50 to 99 mol% of units of monoethylenically unsaturated (a) C3- to C8-monocarboxylic acids, monoethylenically unsaturated C4- to C8-dicarboxylic acids, hemiesters of monoethylenically unsaturated C4- to C8-dicarboxylic acids, esters of monoethylenically unsaturated C3- to C8-carboxylic acids, C2- to C30-olefins, styrene, C1- to C3-alkylstyrenes, C1- to C28-alkyl vinyl ethers, vinyl esters of saturated C1- to C8- carboxylic acids or mixtures of units of these monomers and (b) 50 to 1 mol% of units of amides of monoethylenically unsaturated C3- to C8-carboxylic acids with amide groups of the structure … … in which R = C8- to C28- alkyl, … … R , R = H, CH3, C2H5 R = C1- to C28-alkyl, n = 2 to 100 and R = H, R have K values of 8 to 200, or of salts of these copolymers, as additive to liquid detergent compositions in an amount of 0.1 to 20% by weight and aqueous liquid detergent compositions which contain these copolymers.
