    摘要: Described are monomer compositions containing aspartic acid and other comonomers, such as monosodium aspartate, and methods for their production. The monomer compositions can be polymerized, particularly by thermal polymerization, to obtain useful and novel imide-containing polyamino acids, i.e., copolymers containing polymerized aspartate units and succinimide units. The invention is also directed to the resulting polymeric materials, their methods of production, and their uses and the derivatized polymeric materials by nucleophilic or electrophilic addition. Uses of the imide-containing polyamino acids include, for example, dispersants in detergents and cleansers, water-treatment chemicals as anti-scalants and corrosion inhibitors, personal-care additives for softening and moisturizing, and many others.

    摘要: The present invention provides a method of inhibiting corrosion of ferrous metals in aqueous systems. The corrosion is inhibited by adding an effective amount of one or more poly(amino acids) to the aqueous system. Aqueous systems include for example water treatment systems and equipment used for detergent applications. The poly(amino acids) comprise a reaction product of at least one compound selected from amino acids, amic acids, ammonium salts of monoethylenically unsaturated dicarboxylic acids, ammonium salts of hydroxypolycarboxylic acids and combinations thereof.In one embodiment the poly(amino acids) are added to detergent solutions to inhibit corrosion in equipment for detergent applications. In another embodiment, corrosion inhibitors comprising one or more homopolymers of amino acids and one or more pyrophosphates are added to aqueous systems to inhibit corrosion.
