Abstract

The present disclosure relates to a super absorbent polymer and a method for preparing the same. More specifically, it relates to a super absorbent polymer including a plurality of micropores, specifically an average of 7 or more micropores per particle, having an average diameter of 100 μm or less and a maximum diameter of 300 μm or less, and thus exhibiting an improved absorption rate and a high surface tension, and a method for preparing the super absorbent polymer.
