Synthesis of superabsorbent from cotton cellulose was investigated in 8% LiCL/NMP solvent with the reaction of SA. When DMAP was used for esterification catalyst, hydrogel was obtained without any specific crosslinking agent, which indicated the formation of diester. The product absorbed pure water about 400times for its dry weight, which is comparable with the conventional crosslinked sodium polyacrylate supersbsorbent. Further, the dependence of NaCl concentration of the present superabsorbent was somewhat lower than that of the conventional one, which is very important concerning to the hygiene application. Superabsorbents of the present study biologically degraded almost completely after 25days. This result shows that the superabsorbent of the present study has the excellent biodegradability.
