Abstract: A continuous process for preparing polymers is provided: The continuous process produces polymers from monoethylenically unsaturated acids or anhydrides, and a nitrogen-containing compound, optionally in the presence of a fluidizing agent. The polymers are useful as detergent additives, pigment and mineral dispersants, additives for fertilizers, and corrosion and scale inhibitors in boilers and cooling towers.

Abstract: This invention relates to a process for stripping polymer reaction compositions. The process reduces gel in the polymer reaction composition by adjusting the pH of the polymer to from 7 to 11 prior to stripping and maintaining the adjusted pH during stripping, maintaining the temperature of the polymer at from 30°C to 70°C during stripping, utilizing a continuous stripping operation, or combinations thereof.
Abstract translation: 本发明涉及一种汽提聚合物反应组合物的方法。 该方法通过在汽提之前将聚合物的pH调节至7至11，并在汽提期间保持调节的pH，从而降低聚合物反应组合物中的凝胶，在汽提过程中将聚合物的温度保持在30℃至70℃， 利用连续剥离操作或其组合。

Abstract: 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.
