Preparation of Super Absorbent Resin by Graft Copolymerization of Carboxymethyl Cellulose and Acrylamide

The super absorbent resin was prepared through free radical grafting copolymerization by using carboxymethyl cellulose and acrylamide as material and adopted oxidation reduction initiation system . The effect of the preparation conditions of the resin such as the ratio of the materials, the concentration of the initiator, the concentration of the crossing agent, the temprature of polyrization, partical size of resin etc. to the water absorbent ability of the resin were investigated. The optimal synthetic conditions were selected.
