    • Improved hydrophilic materials, such as foams and films, are provided. These material find use in a wide variety of fluid absorbent products, especially those relating to the absorption of bodily fluids. The soft, absorbent, and resilient foams of this invention exhibit greater wet and dry mechanical strength when compared with those known in the art, as well as improved fluid wicking capacity and lower density. These improved properties are believed attributable to the incorporation into the foams of at least one polyfunctional aliphatic amine.
      The provided hydrophilic materials comprise the polymeric reaction product of a mixture which comprises at least one epoxy resin, at least one amine-terminated poly(alkylene oxide), and at least one polyfunctional aliphatic amine. Methods for preparing foams and other hydrophilic materials are also provided. In general, hydrophilic materials are prepared by providing at least one epoxy resin, forming a reaction mixture by contacting the epoxy resin with at least one amine-terminated poly(alkylene oxide) and at least one polyfunctional aliphatic amine, and curing the reaction mixture.
    • 提供改进的亲水材料,如泡沫和薄膜。 这些材料可用于各种各样的液体吸收产品,特别是与体液吸收相关的产品。 与本领域已知的那些相比,本发明的柔软,吸收和弹性泡沫表现出更大的湿和干的机械强度,以及改进的流体芯吸能力和较低的密度。 这些改进的性质被认为归因于掺入到至少一种多官能脂族胺的泡沫中。 提供的亲水材料包括混合物的聚合反应产物,其包含至少一种环氧树脂,至少一种胺封端的聚(环氧烷)和至少一种多官能脂族胺。 还提供了制备泡沫和其它亲水材料的方法。 通常,通过提供至少一种环氧树脂制备亲水材料,通过使环氧树脂与至少一种胺封端的聚(环氧烷)和至少一种多官能脂族胺接触并使该反应混合物固化形成反应混合物。
