Abstract
Provided is a method of preparing a superabsorbent polymer, which includes carrying out a polymerization of a water-soluble ethylene-based unsaturated monomer to form a water-containing gel polymer, and a step of pulverizing the water-containing gel polymer. In the method of preparing a superabsorbent polymer, an interpenetrating polymer network (IPN) is formed on the surface of the superabsorbent polymer during formation of a surface-crosslinked layer of the superabsorbent polymer, thereby improving physical properties of the superabsorbent polymer.
