The use of ~a-alanine-N,N-diacetic acids as builders in textile-washing powders or as Ca sequestrants in oral hygiene compsns. is specifically excluded. Also claimed are 2-alkylglycine-N,N-diacetonitriles or 2-alkylglycinenitrile -N,N-diacetonitriles (where alkyl = 1-20C alkyl or 2-20 C alkenyl); and cpds. of formula (II). X = carboxylic acid or nitrile function. Cpds. of formula (I) are new except when R = 1-3C alkyl and A = chemical bond.

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.
