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.

摘要： The present invention relates to an acid catalyzed thermal polycondensation process for producing amino acid polymers. More specifically, amino acid polymers are produced by thermally condensing a mixture of one or more amino acids and optionally one or more polyfunctional monomers, using an acid catalyst, while maintaining an intimate admixture. Processing techniques useful for maintaining an intimate admixture include adding to the mixture one or more processing aids, using mechanical means, and combinations thereof. The amino acid polymers produced by this process are useful as cleaning and detergent additives; fertilizer and pesticide additives; personal care product additives; dispersants for inorganic particulates, aqueous emulsions, and drilling muds; and water treatment and oil. production operation additives as corrosion and scale inhibitors
