    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.

    摘要: This invention provides novel water-soluble terpolymers. These terpolymers contain as polymerized units(a) from about 92 to about 30 percent by weight of one or more C.sub.3 -C.sub.6 monoethylenically unsaturated carboxylic acids;(b) from about 5 to about 50 percent by weight of one or more aminoacryloyl derivatives; and(c) from about 3 to about 25 percent by weight of one or more monoethylenically unsaturated monomers polymerizable with (a) and (b). These terpolymers are useful in detergent formulations, particularly automatic machine dishwashing detergent formulations.
