Title:
METHOD FOR PRODUCING SUPER ABSORBENT POLYMER
Document Type and Number:
WIPO Patent Application WO/2020/122559
Kind Code:
A1
Abstract:
The present invention relates to a method for producing a super absorbent polymer. More specifically, the present invention relates to a method for producing a super absorbent polymer, which has improved initial absorption capacity and can exhibit a high absorption rate, by polymerizing a monomer, in which a portion of acidic groups have been neutralized with a basic substance including potassium hydroxide, in the presence of an encapsulated foaming agent.
