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 method of preparing super absorbent polymer includes carrying out a crosslinking polymerization of a monomer mixture comprising a water-soluble ethylenically unsaturated monomer having at least partially neutralized acidic groups, a forming agent, a foam-promoting agent and a silicone-based surfactant in the presence of an internal crosslinking agent to form a hydrogel polymer; drying, pulverizing and classifying the hydrogel polymer to form a base polymer powder; and further crosslinking a surface of the base polymer powder in the presence of a surface crosslinking agent to form a surface crosslinked layer. The method produces super absorbent polymer having not only an excellent absorbent capacity and an absorbency under load but also the rewetting phenomenon can be effectively prevented.

The present invention relates to a method for preparing a superabsorbent polymer, and a superabsorbent polymer prepared thereby. A superabsorbent polymer prepared by the preparation method exhibits minimized deterioration of physical properties after being pulverized, and thus basic absorbance performance is excellent and an excellent liquid permeability and absorbance rate can be exhibited.
