Abstract
The present invention relates to a method for preparing a super absorbent polymer. The method for preparing a super absorbent polymer according to the present invention can provide a super absorbent resin exhibiting fast absorption rate and high saline flow conductivity while having excellent absorption properties such as a centrifuge retention capacity and an absorbency under pressure, by using the polycarboxylic acid-based copolymer under pulverization of the hydrous gel phase polymer.
