| Abstract: | This paper deals with a process of preparing superabsorbent from carboxymethyl cellulose crosslinked with N-methylol acrylamide.The effects of the structure,the degree of crossliaking and the amount of solvent on the absorbency of the products were discussed.The absorbent mechanism of the products for water and saline solution was explained.It has been found that the superabsorbency with a WRV of 200-260 ml/g and SRV of 60-67 ml/g could be achieved by the method described. |
