MÉTODO PARA LA PREPARACIÓN DE POLÍMERO SUPERABSORBENTE

Se provee un método para la preparación de polímero superabsorbente. El método comprende los pasos de, preparar una resina base mediante el agregado de por lo menos uno de los compuestos representados por la siguiente fórmula (1) al polímero reticulado de hidrogel; y secar la resina base. fórmula (1): X-(R)ₙ-Y. A method for preparing a superabsorbent polymer comprises the steps of: preparing a base resin by adding at least one among the compounds represented by the following chemical formula (1) to a hydrogel-phase cross-linked polymer; and preparing a superabsorbent polymer by drying the base resin. The method for preparing a superabsorbent polymer can provide a superabsorbent polymer having not undergone surface cross-linking treatment. The superabsorbent polymer having not undergone surface cross-linking treatment has centrifuge retention capacity (CRC) and absorbency under pressure (AUP), which are equivalent to those of a superabsorbent polymer having undergone surface cross-linking treatment, and has extractable content (EC) and remaining monomers (RM), which decrease in comparison with the superabsorbent polymer having undergone surface cross-linking treatment. X-(R)n-Y (In formula, X is an unsaturated hydrocarbon group or a derivative thereof; R is at least one divalent group selected from a C1-C5 alkylene group, a C1-C4 alkylene oxy group, a C2-C6 alkylene (oxy)carbonyl group and a C2-C5 carbonyloxy group; n is an integer of 1-20; and Y is a hydrophilic group)
