Abstract:
The present invention relates to a method for a super absorbent polymer. The method for preparing a super absorbent polymer according to the present invention makes it possible to provide a super absorbent polymer in which characteristics such as a centrifuge retention capacity and an absorption rate are improved in a balanced manner.

Claim (Index 1):
A method for preparing a super absorbent polymer, the method comprising the steps of:\n forming a first hydrogel polymer containing a crosslinked polymer of acrylic acid or its salt, and having a first centrifuge retention capacity (CRC; g/g) for a physiological saline solution measured in accordance with EDANA recommended test method No. WSP 241.2 and a first absorption rate (sec) measured according to the vortex test carried out under conditions of stirring 50 ml of 0.9 wt % NaCl solution at a rate of 600 rpm; forming a second hydrogel polymer containing a crosslinked polymer of acrylic acid or its salt, and having a second centrifuge retention capacity (CRC; g/g) in which a difference between the first centrifuge retention capacity and the second centrifuge retention capacity is \u22122 g/g to 2 g/g, and a second absorption rate (sec) in which a difference between the first absorption rate and the second absorption rate is 5 sec or more. forming a mixture of the first hydrogel polymer and the second hydrogel polymer; drying the polymer mixture; pulverizing the dried polymer mixture; and surface-crosslinking the pulverized polymer mixture.
