Title:
PREPARATION METHOD FOR SUPER ABSORBENT POLYMER
Document Type and Number:
WIPO Patent Application WO/2023/120907
Kind Code:
A1
Abstract:
The present invention relates to a preparation method for a super absorbent polymer capable of minimizing loss of air bubbles during foaming polymerization through radical polymerization. According to the preparation method of the present invention, a large number of small and uniform pores are formed to prepare a super absorbent polymer having a high surface area, and the super absorbent polymer exhibits an excellent absorption rate, and thus can be used in various products requiring high absorption properties.
