Method for preparing super absorbent resin

A method for preparing a superabsorbent polymer comprising:

• a) preparing a hydrogel phase polymer by thermopolymerizing or photopolymerizing a monomer composition including a water-soluble ethylenically unsaturated monomer and a polymerization initiator;
• b) chopping the hydrogel phase polymer to form a chopped hydrogel phase polymer;
• c) adding particles to the chopped hydrogel phase polymer to form a particle-added hydrogel phase polymer,
• wherein the particles have a i) BET specific surface area of 300 m2/g to 1500 m2/g and ii) porosity of 50% or greater;
• d) chopping the particle-added hydrogel phase polymer again to form an additionally chopped hydrogel phase polymer;
• e) drying the additionally chopped hydrogel phase polymer to form a dried hydrogel phase polymer;
• f) milling the dried hydrogel phase polymer to form a milled hydrogel phase polymer;
• g) adding a surface crosslinking agent to the milled hydrogel phase polymer;
• and
• h) carrying out a surface crosslinking reaction,
• wherein the surface crosslinking agent does not contain an organic solvent.
