摘要：
The present invention relates to a super absorbent polymer exhibiting more improved liquid permeability and/or absorption rate while maintaining excellent absorption performance. Such super absorbent polymer comprises a base polymer powder including a first cross-linked 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 polymer powder and including a second cross-linked polymer in which the first cross-linked polymer is further cross-linked through an alkylene carbonate having 2 to 5 carbon atoms, and satisfies predetermined physical properties.
