Using ammonium eerie nitrate as initiator, the superabsorbent composite of carboxymethl cellulose(CMC) grafted acrylamide/kaolin was synthesized by water solution polymerization. The effect of the ratio of carboxymethyl cellulose/acrylamide, the amount of initiator and cross linking agent, kaolin and sodium hydroxide on water absorption was discussed. The structure of superab-sorbent composites was characterized by FYIR and their morphology was observed by electron microscope. The results showed that the su...
