| titleOfInvention | PROCESS FOR THE PREPARATION OF SUPERABSORBENT POLYMER |
| abstract | The present invention provides a method for producing a superabsorbent resin which enables production of a superabsorbent resin capable of exhibiting an excellent absorption rate including a uniform porous structure through a simple and economical process. The method for producing a superabsorbent resin includes crosslinking a water-soluble ethylenically unsaturated monomer having at least partially neutralized acid groups in the presence of an internal crosslinking agent to form a hydrogel polymer comprising a first crosslinked polymer; Drying and pulverizing the hydrogel polymer; The pulverized polymer is classified into polymer particles having a particle diameter of at least 10 to 150 mu m , polymer particles having a particle diameter of 150 to 200 mu m , and polymer particles having a particle diameter of 200 to 850 mu m to obtain a base resin powder ; And cross-linking the base resin powder. In the cross-linking polymerization step, the foaming polymerization is carried out in the presence of polymer particles having an average particle diameter of 10 to 200 μm and an anionic surfactant obtained in the classification step. |
