    摘要: Polyacetals useful as detergent additives contain units of the formula ##STR1## where R is hydrogen, C.sub.1 -C.sub.4 -alkyl or COOM,M is C.sub.1 -C.sub.4 -alkyl or an alkali metal, ammonium or alkanolamine group, andm is from 0 to 9,have K values (determined by the method of H. Fikentscher on the sodium salt in 1% strength by weight aqueous solution at 25.degree. C. and pH 7) of at least 8.5, and are prepared by polymerizing compounds of the formula ##STR2## where R is hydrogen, C.sub.1 -C.sub.4 -alkyl or COOM,M is C.sub.1 -C.sub.4 -alkyl or an alkali metal, ammonium or alkanolamine group,R.sup.2 is C.sub.1 -C.sub.4 -alkyl, andm is from 0 to 9,in the presence of initiators and optionally comonomers with or without hydrolysis of the ester groups.

    摘要: Process for preparing polycondensates of citric acid and/or isocitric acid, by converting(a) citric acid, isocitric acid or mixtures thereof in an organic solvent in the presence of a water-withdrawing agent at least partially into the anhydride form and then condensing the reaction mixture, if desired after addition of two cocondensable compounds selected from the group consisting of(b) other hydroxycarboxylic acids and/or(c) amino acids, alcohols, amines and/or at least dibasic carboxylic acids other than carboxylic acids (a) and (b), at temperatures of at least 80.degree. C. to form polycarboxylates which have an average molecular weight of at least 500, polycondensates of citric acid and/or isocitric acid obtainable thereby, anduse of said polycondensates as ingredients in phosphate-free and reduced-phosphate detergents and cleaners, and also detergents and cleaners which contain at least one surfactant and optionally builders and other customary constituents with from 0.1 to 30% by weight of an abovementioned polyestercarboxylate.
