    • A process is provided for preparing a dispersion of a polyamide in water, said process comprising: dissolving a polyamide having an amine value of greater than about 2 in an organic solvent to form a solution of said polyamide in said solvent, said polyamide and said solvent being at a temperature below the softening point of, said polyamide during said dissolving, said solution further comprising a surfactant and an inorganic alkaline material, adding sufficient water containing an acid to said solution with mixing to form an oil-in-water dispersion, the temperature of said solution and said water being below the softening point of said polyamide during said adding, the amount of said acid being sufficient to neutralize a portion of said inorganic alkaline material, but insufficient to coagulate said polyamide from the resulting oil-in-water dispersion, and removing at least a major amount of said organic solvent from said oil-in-water dispersion. The resulting dispersion is useful in preparing a coating of the polyamide, which coating is useful as an adhesive.
    • 提供了一种制备聚酰胺在水中的分散体的方法,所述方法包括:将具有大于约2的胺值的聚酰胺溶解在有机溶剂中以形成所述聚酰胺在所述溶剂中的溶液,所述聚酰胺和所述溶剂 在所述溶解期间处于低于所述聚酰胺的软化点的温度下,所述溶液还包含表面活性剂和无机碱性材料,在混合下向所述溶液中加入足够的含有酸的水以形成水包油分散体, 所述溶液的温度和所述水在所述添加期间低于所述聚酰胺的软化点,所述酸的量足以中和所述无机碱性物质的一部分,但不足以使所述聚酰胺从所得水包油中凝结 分散,并从所述水包油分散体中除去至少大量的所述有机溶剂。 得到的分散体可用于制备聚酰胺的涂层,该涂层可用作粘合剂。
