| Abstract: | The cellulose of bleached pulp is used as the raw material to prepare superabsorbent resin by grafting copolymerization with the acrylic acid.Some process conditions such as the dosages of monomer and initiator,neutraliztion degree and reaction temperature were investigated.The optimal reaction conditions were obtained and the copolymer structure was characterized by IR.The resin could absorb 550 times water as its own mass and had very good water retention ability. |
