Title: SUPERABSORBENT RESIN
Abstract:
The present invention relates to a superabsorbent resin, which maintains excellent absorption performance and retains excellent physical properties even after being physically damaged by an external force. The superabsorbent resin comprises: a base resin powder comprising a first cross-linked polymer of a water-soluble ethylenically unsaturated monomer having an at least partially neutralized acidic group; and a surface cross-linked layer formed on the base resin powder and comprising a second cross-linked polymer obtained by additionally cross-linking the first cross-linked polymer via an alkylene carbonate having 2 to 5 carbon atoms, wherein the superabsorbent resin satisfies predetermined physical properties.
