Modified polyaspartic acids, preparation thereof and use thereof

摘要: Modified polyaspartic acids useful as detergent and cleaner additives, water treatment agents scale inhibitors in the evaporation of sugar juice are obtainable by polycondensation (a) from 1 to 99.9 mol % aspartic acid with (b) 99 0.1 fatty acids, polybasic carboxylic anhydrides hydroxycarboxylic monobasic polyhydroxycarboxylic alcohols, amines, alkoxylated alcohols amino sugars, carbohydrates, sugarcarboxylic and/or non-proteinogenic aminocarboxylic or polymerizing monoethylenically unsaturated monomers presence manner a free-radically initiated graft polymerization.
