    • 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.
    • 本发明涉及用于生产氨基酸聚合物的酸催化的热缩聚方法。 更具体地,氨基酸聚合物通过使用酸催化剂将一种或多种氨基酸和任选的一种或多种多官能单体的混合物进行热缩合同时保持紧密的混合物来制备。 用于保持紧密混合物的加工技术包括使用机械方法将混合物加入到一种或多种加工助剂中,及其组合。 通过该方法生产的氨基酸聚合物可用作清洁剂和洗涤剂添加剂; 化肥和农药添加剂; 个人护理产品添加剂; 无机颗粒分散剂,水乳液和钻井泥浆; 以及水处理和石油生产操作添加剂作为腐蚀和阻垢剂。
