Abstract
The present disclosure relates to a super absorbent polymer, including: a base resin powder comprising a first cross-linked polymer of a water soluble ethylene-based unsaturated monomer containing acidic groups which are at least partially neutralized; and a surface cross-linked layer comprising a second cross-linked polymer further cross-linked from the first cross-linked polymer and formed on the base resin powder, wherein the first cross-linked polymer is bound to a porous zeolite in which a mesopore having a BET surface area of at least 100 m/g and a porosity of at least 0.2 cm/g is formed, and a preparation method thereof.
