Abstract
Disclosed are a method of preparing a superabsorbent polymer that includes a fine-powder regranulate and has improved properties owing to the use of an additive, and a superabsorbent polymer prepared thereby, wherein the superabsorbent polymer can exhibit improved properties, including high centrifugal retention capacity (CRC) and fine-powder agglomeration strength, without decreasing absorption under pressure (AUP) or permeability, compared to when no additive is used during the formation of a fine-powder regranulate, and furthermore, the fine powder is recycled, thus reducing processing costs, thereby generating economic benefits.
