Title:
PREPARATION METHOD FOR SUPER ABSORBENT POLYMER
Document Type and Number:
WIPO Patent Application WO/2022/131836
Kind Code:
A1
Abstract:
The present invention relates to a preparation method for a super absorbent polymer. More specifically, according to the preparation method, when a polymerization reaction of monomers proceeds in the presence of an aqueous dispersion of hydrophobic particles, a super absorbent polymer that exhibits an improved absorption rate without deterioration in absorption properties can be prepared.
