Abstract
Disclosed are a superabsorbent polymer having improved anti-caking properties and a method of preparing the same, and the superabsorbent polymer having improved anti-caking properties includes a superabsorbent polymer, microparticles, and water, and to improve anti-caking properties of the superabsorbent polymer, the temperature of the superabsorbent polymer or water upon addition of water or the aging time upon stirring is adjusted, thereby preventing caking of the particles.
