A super absorbent polymer according to the present invention has excellent dryness while maintaining excellent absorption performance, and thus is preferably used for hygienic materials such as diapers, and can exhibit excellent performance.

Super absorbent polymer

Provided are a superabsorbent polymer and a preparation method thereof. According to the present invention, a superabsorbent polymer having high centrifuge retention capacity and absorption rate may be prepared by using a specific foam stabilizer.

Superabsorbent polymer and preparation method thereof

A super absorbent polymer according to the present invention has an excellent discoloration resistance characteristic even under high temperature/high humidity conditions, while maintaining excellent absorption performance, and is preferably used for hygienic materials such as diapers, and thus can exhibit excellent performance.

Super absorbent polymer and method for producing same

The present invention relates to a superabsorbent polymer which exhibits more improved liquid permeability while maintaining excellent absorption performance, and suppresses aggregation and caking of particles even under high temperature/high humidity conditions, and to a method for producing the same. The super absorbent polymer comprises: a base polymer powder including a first crosslinked polymer of a water-soluble ethylenically unsaturated monomer having at least partially neutralized acidic groups; and a surface crosslinked layer formed on the base polymer powder and including a second cross-linked polymer in which the first cross-linked polymer is further crosslinked via a surface cross-linking agent, wherein the super absorbent polymer includes aluminum sulfate dispersed in the surface crosslinked layer and alumina dispersed on the surface crosslinked layer.

The super absorbent polymer according to the present invention has reduced 3-hour saline solution re-wet while having a high absorption rate and absorption against pulp, and thus can be used for hygienic materials such as diapers, thereby exhibiting excellent performance.

Super absorbent polymer and preparation method thereof

A super absorbent polymer produced by the preparation method of the super absorbent polymer according to the present invention has excellent dryness while maintaining excellent absorption performance, and thus is preferably used for hygienic materials such as diapers and can exhibit excellent performance.

Method for producing super absorbent polymer

A superabsorbent polymer according to the present invention has excellent initial absorption properties, and thus it may be used in sanitary materials such as diapers, etc., thereby exhibiting excellent performances.

Method of preparing superabsorbent polymer

A superabsorbent polymer having high centrifuge retention capacity and absorption rate prepared by using a particular foam stabilizer and a polymerization initiator. The foam stabilizer includes a sucrose ester and a polyalkylene oxide, and polymerization initiator includes a photoinitiator and a cationic azo-based initiator.
