VERWENDUNG VON PFROPFCOPOLYMEREN ALS ZUSATZ ZU PHOSPATFREIEN ODER PHOSPHATARMEN WASCH- UND REINIGUNGSMITTELN

摘要

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.
