Title:

METHOD FOR PREPARING SUPER ABSORBENT POLYMER

Document Type and Number:

WIPO Patent Application WO/2022/131834

Kind Code:

A1

Abstract:

The present invention relates to a method for preparing a super absorbent polymer. More specifically, the preparation method enables the preparation of a super absorbent polymer exhibiting a high surface tension and an improved absorption rate without a deterioration in absorption if the polymerization of monomers proceeds in the presence of hydrophobic particle aqueous dispersion.
