| Abstract: | With acrylamide(AM) and 2-acrylamido-2-methyl propane sulfonic acid(AMPS) as raw material,and N,N′-methylene-bis-acrylmide(NMBA) as crosslinker,a super absorbent resin(PAMA) was prepared by ultrasonic irradiation polymerization.The results show that when the mass fraction of monomer AM is 25%,pH value in reaction system is 2.0,reaction temperature is 45 ℃,and the mass fraction of crosslinker is 0.01%,the water absorption of the PAMA copolymer can achieve 1 326 g/g.The molecular structure of the copolymer was characterized by FT-IR and polarizing optical microscopy. |
