Date Mar. 7, 1996A process for preparing salts of polyaspartic acid by treating polycondensates in aqueous medium with bases, employing at least 0.7 equivalent of an alkali metal and/or alkaline earth metal base per mole of the aspartimide, aspartic acid and/or aspartamide units present in the polycondensates, and the bases being added within from 30 min to 20 hours to an aqueous suspension of polycondensates of aspartic acid which has been heated to 40 DEG -140 DEG C., and the reaction mixture being allowed to react further where appropriate, and the use of alkali metal and/or alkaline earth metal salts of polyaspartic acids obtainable by treating polycondensates of aspartic acid in aqueous medium with more than 1 equivalent of an alkali metal and/or alkaline earth metal base, with the molecular weight of the polycondensates being reduced, as additive to detergents and cleaners.

    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.
