Preparation method of super absorbent polymer |
| abstract |
The present invention relates to a method for producing a superabsorbent resin exhibiting improved liquid permeability and / or absorption rate while maintaining excellent absorption performance. Such a superabsorbent resin comprises: a base resin powder comprising a first crosslinked polymer of a water-soluble ethylenically unsaturated monomer having at least partially neutralized acidic groups; And a surface cross-linked layer formed on the base resin powder, wherein the first cross-linked polymer comprises a second cross-linked polymer that is additionally cross-linked through an alkylene carbonate having 2 to 5 carbon atoms, To meet the physical properties of. |
