Document Type and Number:
WIPO Patent Application WO/2016/093643
Kind Code:
A8
Abstract:
The present invention relates to a method for preparing a superabsorbent polymer. According to the present invention, the method for preparing a superabsorbent polymer carries out, with respect to a polymer obtained by polymerizing ethylenically unsaturated monomers, a re-granulation step by mixing water and a compound of a specific chemical formula. According to the present invention, provided is a method for preparing a superabsorbent polymer, capable of improving the quality of a final resin since the moisture retention capacity thereof is improved and the amount of remaining monomers is reduced.
