Abstract: Using N,N’-methylene-bis-acrylmide(NMBA) as a crosslinker, a superabsorbent, polymer PAMA based on acrylamide(AM) and 2-acrylamido-2-methylpropanesulfor acid(AMPS) as monomers, was prepared by ultrasonic irradiation polymerization without initiator and nitrogen atmosphere.The molecular structure was characterized by FT-IR, and the absorbance properties of resin was compared with that by microwave irridation polymerization and thermal polymerization. The results showed that the resin prepared by ultrasonic irradiation polymerization has excellent water absorption, monomer convertion,water retention and absorbency rate.
