SUPERABSORBENT POLYMER AND PREPARATION METHOD THEREFOR

摘要

The present invention relates to a superabsorbent polymer and a preparation method therefor. According to the present invention, the superabsorbent polymer with improved centrifuge retention capacity (CRC) and absorption under load (AUL) can be prepared by controlling the shape and size of chopper die holes when a hydrogel-phase polymer is coarsely pulverized.
