  • Patent number: 10850260
    Abstract: A super absorbent polymer and a method for producing the same are disclosed herein. In some embodiments, the super absorbent polymer includes a base polymer powder including a cross-linked polymer, and first and second surface cross-linked layers formed on the base polymer powder. The first and second surface cross-linked layers are formed by further cross-linking the cross-linked polymer in the presence of a surface crosslinking agent, wherein the first and second surface cross-linked layers each include a cross-linked structure derived from epoxy-based and non-epoxy-based surface crosslinking agents. The super absorbent polymer can exhibit excellent absorbent properties even in a swollen state and thus exhibit excellent anti-rewetting effects. Accordingly, when the super absorbent polymer is used, it is possible to provide a sanitary material such as a diaper or a sanitary napkin which can give a smooth touch feeling even after the body fluid is discharged.

  • Patent number: 10759912
    Abstract: Provided are a superabsorbent polymer and a preparation method thereof. The superabsorbent polymer may effectively avoid a rewetting phenomenon after absorbing liquid, because a saline solution hardly remains in the empty spaces between swollen gel particles. Accordingly, the superabsorbent polymer may be used to provide hygienic materials, such as diapers, sanitary napkins, etc., which have a fluffy texture even after body fluid is discharged thereto.
