Abstract

La presente invención se refiere a un método para preparar un polímero súperabsorbente. El método para preparar un polímero súperabsorbente de acuerdo con la presente invención comprende las etapas de: preparar un polímero de hidrogel mediante una polimerización térmica o una fotopolimerización de una composición de monómeros que incluye un monómero insaturado a base de etileno soluble en agua y un iniciador de polimerización; secar el polímero de hidrogel; pulverizar el polímero seco; mezclar el polímero pulverizado con un agente de reticulación de superficie y una partícula de polímero que tiene una estructura de núcleo-cubierta; y realizar una reacción de reticulación de superficie. De acuerdo con la presente invención, el polímero súperabsorbente que tiene permeabilidad mejorada se puede obtener mediante la adición de la partícula de polímero durante la reticulación de superficie.
