Abstract:
A preparation method of a superabsorbent polymer, and a superabsorbent polymer prepared thereby are provided. The preparation method of the superabsorbent polymer according to the present disclosure prevents polymer particles from being broken or the surface thereof from being damaged during preparation and handling of the superabsorbent polymer, thereby providing a superabsorbent polymer having excellent absorption properties and permeability.

Claim (Index 8):
The preparation method of the superabsorbent polymer of  claim 1 , wherein the surface crosslinking is performed by reacting one or more surface crosslinking agents selected from the group consisting of ethylene glycol diglycidyl ether, polyethylene glycol diglycidyl ether, glycerol polyglycidyl ether, propylene glycol diglycidyl ether, polypropylene glycol diglycidyl ether, ethylene carbonate, ethylene glycol, diethylene glycol, propylene glycol, triethylene glycol, tetraethylene glycol, propanediol, dipropylene glycol, polypropylene glycol, glycerin, polyglycerin, butanediol, heptanediol, hexanediol trimethylol propane, pentaerythritol, sorbitol, calcium hydroxide, magnesium hydroxide, aluminum hydroxide, iron hydroxide, calcium chloride, magnesium chloride, aluminum chloride, and iron chloride.
