Abstract
The super absorbent polymer comprises: a base polymer powder including a first crosslinked 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 crosslinked polymer in which the first crosslinked polymer is further crosslinked via a surface crosslinking agent, wherein the super absorbent polymer has: a fixed height absorption (FHA) of 22.5 g/g to 29 g/g, a saline flow conductivity (SFC) of 35 (·10cm·s/g) or more, and T-20 of 180 seconds or less.
