| Abstract: | A superabsorbent resistant to saline solution was prepared from copolymer of sodium acrylate with sodium polymannuronate. The effects of the amount of sodium polymannuronate and initiator , degree of neutralization of acrylic acid, mole ratio of KOH to Na 2CO 3 on water absorbency(WA) and the hydrogel modulus of the copolymer were investigated. The results showed that WA of the superabsorbent was about 1 000 and 85 times its own mass respectively, if the superabsorbent was allowed to swell in distilled water and 0 9%(mass fraction) aqueous NaCl at room temperature for 30 min. The superabsorbent also had excellent hydrogel modulus. |
