Preparation of Cellulose-Graft Superabsorbent Resin
Abstract:
In order to prepare a novel superabsorbent resin based on cellulose, straw pulp cellulose was used as raw material, through etherification preparation of carboxymethyl cellulose, K2S2O8-Na2SO3 oxidationredox system as an initiator, acrylic acid, acrylamide as grafting monomer, crosslinking agent N, N-methylenebisacrylamide were used to synthesize the high water absorbent resin. The effects of reaction conditions to superabsorbent resin were studied using water absorbencies as evaluation standard, the optimum preparation technology was decided.
