Abstract
The aqueous solution polymerization of acrylic acid, acrylamide and attapulgite clay under microwave irradiation was studied, and a super absorbent resin was synthesized. The factors that influence the liquid absorbency rate of the super absorbent resin were discussed, including microwave irradiation time, neutralization degree of acrylic acid (AA), the dosage of initiator, crosslinking agent and attapulgite clay. The super absorbent resin was characterized by IR and scanning electron microscopy (SEM). It just needs 30 s to preparation the super absorbent resin. Its liquid absorbency rate is about 1620 g.g−1 and 170 g.g−1 in distilled water and 0.9 wt% NaCl solution, respectively.
