Abstract
The present invention relates to a super absorbent resin, and the super absorbent resin can exhibit a fast absorption rate and high gel strength even in a partially swollen state through the size optimization of partially swollen gel particles. Therefore, the use of the super absorbent resin can effectively prevent a rewetting phenomenon.
