Title:
SUPER ABSORBENT POLYMER AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/066338
Kind Code:
A1
Abstract:
The present invention relates to a super-absorbent polymer capable of exhibiting improved bacterial growth inhibition properties without deteriorating physical properties such as centrifuge retention capacity, absorbency under load, etc. of a super-absorbent polymer or increasing dust generation, and a preparation method thereof. The super-absorbent polymer comprises: a base polymer powder including a crosslinked polymer of a water-soluble ethylenically unsaturated monomer containing an acid group in which at least a part of the acid group is neutralized; and a surface crosslinked layer formed on the base resin powder by further crosslinking the crosslinked polymer via a surface crosslinking agent, wherein the crosslinked polymer of the base resin powder or the surface crosslinked layer contains an antimicrobial agent comprising an organic acid salt having an aromatic ring inside the crosslinked structure.
