In this paper, the synthesis of porous superabsorbent was performed using sodium bicarbonate, acetone, and sucrose as porosity generators. Compared to the superabsorbent prepared under porous-free condition, the results showed that porosity generators can improve absorbency rate effectively, and that sodium bicarbonate has a better effect than others. Morphological studies with scanning electron microscope (SEM) showed that the superabsorbent has the loose and porous structure. 
