Abstract
Provided are a superabsorbent polymer and a preparation method thereof. More particularly, provided are a superabsorbent polymer including a fine powder reassembly, wherein the superabsorbent polymer exhibits excellent absorption performances and absorption rate, and does not cause deterioration of physical properties such as water retention capacity (CRC) or absorbency under pressure (AUP), and a preparation method thereof.
