Abstract
The present invention relates to a super absorbent polymer and a method for preparing the same. The present invention has features that it is possible to prepare a super absorbent resin that can have an improved centrifuge retention capacity (CRC) and a high absorbency under load (AUL) by controlling the shape and size of the chopper die holes during coarse pulverization of a hydrous gel phase polymer.
