摘要： Modified polyaspartic acids are obtained by polycondensing (a) 1 to 99.9 mol % aspartic acid with (b) 99 to 0.1 mol % 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, sugar carboxylic acids and/or non-proteinogenic aminocarboxylic acids, or by polymerising monoethylenically unsaturated monomers in the presence of polyaspartic acids, in the manner of radically initiated graft copolymerisation. Also disclosed is a process for preparing these modified polyaspartic acids, as well as the use of these modified polyaspartic acids as additives to washing and cleaning agents, as water conditioning agents and as deposit inhibitors during the condensation of sugar juice.

摘要： 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.

摘要： Polyasparaginic acid and condensates of asparaginic acid containing up to 40 % by moles of other condensed aminoacids, as well as the alkali and ammonium salts of these condensates and of polyasparaginic acid, are used in cleaning product formulations for cleaning machines in food and beverage industry installations. Also disclosed are aqueous cleaning product formulations which contain (1) 0.05 to 30 % by weight polyasparaginic acid, condensates of asparaginic acid containing up to 40 % by moles of other condensed aminoacids, the alkali and ammonium salts of said condensates and/or of polyasparaginic acid; (b) 2 to 50 % by weight alkali metal hydroxide, carbonate or silicate or their mixtures and (c) 1 to 30 % by weight surfactants.
