    Abstract: PCT No. PCT/EP93/01588 Sec. 371 Date Jan. 3, 1995 Sec. 102(e) Date Jan. 3, 1995 PCT Filed Jun. 22, 1993 PCT Pub. No. WO94/01486 PCT Pub. Date Jan. 20, 1994Modified polyaspartic acids useful as detergent and cleaner additives, as water treatment agents and as scale inhibitors in the evaporation of sugar juice are obtainable by polycondensation of (a) from 1 to 99.9 mol % of aspartic acid with (b) from 99 to 0.1 mol % of fatty acids, polybasic carboxylic acids, anhydrides of polybasic carboxylic acids, polybasic hydroxycarboxylic acids, monobasic polyhydroxycarboxylic acids, alcohols, amines, alkoxylated alcohols and amines, amino sugars, carbohydrates, sugarcarboxylic acids and/or non-proteinogenic aminocarboxylic acids or by polymerizing monoethylenically unsaturated monomers in the presence of polyaspartic acids in the manner of a free-radically initiated graft polymerization.

    Abstract: The invention concerns polyacetal-block-containing polymers obtained by polymerizing, in the presence of initiators, carboxylic acid esters containing aldehyde groups and by reacting the polymers with at least bifunctional cross-linking agents, in the presence of acids or Lewis acids and optionally hydrolysing the ester groups thus incorporated in the polymer. The invention also concerns a method of producing polymers containing polyacetal blocks by polymerizing carboxylic acid esters containing aldehyde groups in the presence of initiators and reacting the polyacetals containing terminal hydroxy groups thus obtained with at least bifunctional cross-linking agents, in the presence of acids or Lewis acids, plus the use of the polymers thus obtained as additives in phosphate-free and phosphate-reduced washing and cleaning agents, as scale inhibitors and as dispersants for pigments.
