Abstract
The present disclosure relates to a method for preparing a super absorbent polymer. More specifically, the above method performs a polymerization reaction of a monomer in the presence of an aqueous dispersion of hydrophobic particles, and thus a super absorbent polymer having a high surface tension and an improved absorption rate can be prepared without deterioration in absorption properties.
