Abstract:
The present invention relates to a method for preparing superabsorbent polymer. According to the preparation method of the present invention, the surface penetration depth of a surface crosslinking agent can be appropriately controlled, and superabsorbent polymer with excellent properties can be prepared though homogeneous surface crosslinking. Thus, superabsorbent polymer with improved absorption property can be provided without deterioration of absorbency under load.

Claim (Index 7):
The method for preparing superabsorbent polymer according to  claim 1 , wherein the surface crosslinking reaction is conducted at a temperature of 140 to 220\u00b0 C. for 15 to 120 minutes.
