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.
