Abstract
Provided are a superabsorbent polymer capable of exhibiting improved bacterial growth-inhibitory property without deterioration in physical properties of the superabsorbent polymer, such as water retention capacity and absorbency under pressure, or without an increase in the generation of dust, and a preparation method thereof. The superabsorbent polymer may include a base polymer powder including a crosslinked polymer of water-soluble ethylenically unsaturated monomers including acidic groups, of which at least a part is neutralized; and a surface-crosslinked layer which is obtained by additionally crosslinking the crosslinked polymer via a surface crosslinking agent to be formed on the surface of the base polymer powder, wherein the crosslinked polymer of the base polymer powder or the surface-crosslinked layer includes an antimicrobial agent including an organic acid salt having an aromatic ring inside the crosslinked structure thereof.
