Abstract
The present invention relates to a method for preparing a superabsorbent polymer, and a superabsorbent polymer prepared thereby. A superabsorbent polymer prepared by the preparation method exhibits minimized deterioration of physical properties after being pulverized, and thus basic absorbance performance is excellent and an excellent liquid permeability and absorbance rate can be exhibited.
