    摘要： This invention is directed to a process for making surface treated absorbent gelling material by treating partially swollen absorbent gelling polymers, which have a specific water content with a treatment agent, such as a coating agent, and subsequently removing at least part of the water. The treatment agent thus typically forms a shell on the polymers or part thereof, which can extend when the polymers swell in water; thus, the treatment shell or coating does not rupture when the polymers swell in a liquid, e.g., water or saline water, the coating being extensible in wet state. The treatment agent comprises preferably an elastomeric polymeric material. The invention also relates to surface-treated absorbent gelling material obtainable by the process of the invention, and to products, e.g., disposable absorbent articles, comprising such material.

    摘要翻译： 本发明涉及通过用处理剂例如涂层剂处理具有特定含水量的部分膨胀的吸收胶凝聚合物，然后除去至少部分水来制备表面处理的吸收胶凝材料的方法。 因此，处理剂通常在聚合物或其部分上形成壳，当聚合物在水中溶胀时，其可以延伸; 因此，当聚合物在液体如水或盐水中膨胀时，处理壳或涂层不会破裂，涂层在湿润状态下是可延展的。 处理剂优选包括弹性体聚合材料。 本发明还涉及通过本发明的方法获得的表面处理的吸收性凝胶材料以及包括这种材料的产品，例如一次性吸收制品。
