The present invention relates to a method for preparing superabsorbent polymer that introduces a plate type and rod-shaped clay additive in the superabsorbent polymer, and thus exhibits basic properties of a superabsorbent polymer equivalent to or much better than the existing superabsorbent polymer through multi-crosslinking, and particularly, can improve absorbency under pressure (AUP), and a superabsorbent polymer obtained thereby. |
