| titleOfInvention | Superabsorbent polymer and method for preparing same |
| abstract | The present invention relates to a method for preparing a superabsorbent polymer and a superabsorbent polymer prepared using the preparation method, and more specifically relates to a method for preparing a superabsorbent polymer comprising the steps of: preparing a base resin in which an internal crosslinking agent and an acrylic acid monomer are crosslink polymerized, the acrylic acid monomer having an acidic group of which at least a part has been neutralized; and surface-modifying the base resin by increasing the temperature of the base resin in the presence of a surface crosslinking agent, wherein the internal crosslinking agent comprises a first epoxy crosslinking agent having an epoxy equivalent weight of 100-130g/eq and a second epoxy crosslinking agent having an epoxy equivalent weight of 130g/eq. The present invention also relates to a superabsorbent polymer prepared using the preparation method. The method for preparing a superabsorbent polymer according to the present invention can provide a superabsorbent polymer having improved rewettability and liquid permeability. |
