Abstract: The invention concerns polycocondensates of aspartic acid, obtained by condensing aspartic acid in the presence of carboxylic-group-containing polymers which include at least 10 mol % of a monoethylenically unsaturated carboxylic acid polymerized into the polymer and have a molecular weight of at least 300, in the ratio by weight of 1000:1 to 2:1. The invention also concerns methods of producing such polycocondensates and the use of the polycocondensates, in a form with free acid groups or in a form with the acid groups neutralized with ammonia, amines, alkali-metal bases or alkaline-earth bases, as an additive in washing and cleaning agents, as scale inhibitors or as dispersants for finely divided solids.

Abstract: There are described block copolyacetals obtainable by cationically initiated polyaddition of (A) polyacetals containing acetaldehyde acetal units and having at least 2 OH groups in the molecule and (B) polyacetals containing acetaldehyde acetal units and having at least 2 vinyl ether groups in the molecule. in a molar ratio of (A):(B) of from 2:1 to 1:2, processes for preparing the block copolyacetals by cationically initiated polyaddition of (A) and (B), and the use of the block polyacetals as additament to reduced-phosphate and phosphate-free detergents and cleaners and as low-foam surfactants in dishwashing compositions.
