Abstract: A process is disclosed for preparing products from the reaction of polyasparaginic acid imides with aminoacids by reacting aminoacids with polyasparaginic acid imides in an aqueous medium at pH values at which at least 5% of the amino groups of the aminoacids having a non-protonated form are in equilibrium with those having a protonated form. Also disclosed is the use of the thus obtained reaction products and of products from the reaction of polyasparaginic acid imides with alkanolamines or aminated C1-C30-fatty alcohol alkoxilates which contain up to 50% by moles of polymerized ethylene and/or propylene oxide per mole of fatty alcohol. These products are useful as additives for washing and cleaning agents, as scale inhibitors and as dispersing agents.

Abstract: Process for the preparation of polymers of aspartic acid by reacting (a) maleic anhydride and (b) ammonia and/or primary or secondary amines without diluent in the (a) : (b) molar ratio of 1 : 0.1 to 1 : 3 to give monoamides of maleic acid, fumaric acid or their ammonium salts at up to 100.degree.C and subsequent condensation of the reaction products, with or without compounds capable of cocondensation, at above 100.degree.C and, where appropriate, hydrolysis of the condensates and use of the polymers as scale inhibitor, as dispersants for pigments and as additive to detergents and cleaners.
