Abstract
The present invention relates to superabsorbent polymer and a method for preparing the same. The present invention can provide a superabsorbent polymer in which a hydrophobic material having an HLB of 0-6, a hydrophilic polymer and a surface cross-linking agent are mixed into a base resin, thereby having improved rewetting characteristics and permeability through surface-modification of the base resin.
