Abstract

The present invention relates to a super absorbent polymer exhibiting more improved liquid permeability while maintaining excellent absorption performance, and a method for producing the same. The super absorbent polymer comprises: a base polymer powder comprising a first cross-linked polymer of a water-soluble ethylenically unsaturated monomer having at least partially neutralized acidic groups; and a surface crosslinked layer formed on the base polymer powder and including a second cross-linked polymer in which the first crosslinked polymer is further cross-linked through an alkylene carbonate having two to five carbon atoms. The super absorbent polymer satisfies predetermined physical properties.
