Abstract
Provided are a superabsorbent polymer exhibiting excellent biodegradability without deterioration in physical properties of the superabsorbent polymer, such as water retention capacity, absorbency under pressure, etc., and a preparation method thereof. The biodegradable superabsorbent polymer comprises a base polymer including a crosslinked polymer of a non-modified or acidic group-containing modified polysaccharides and a first crosslinking agent, wherein at least part of the base polymer is crosslinked by a second crosslinking agent, the first crosslinking agent includes a cyclic carboxylic acid anhydride, and the second crosslinking agent includes an epoxy-based compound.
