| Abstract: | High water-absorbing and water-keeping super absorbent was synthesized by graft copolymerizing of the carboxymethyl cellulose with sodium acrylate and crylic acid in presence of persulfate potassium as initiator.The influences of the counteract degree of the crylic acid on the water absorbability was discussed.Through experiments we find the good condition for the water-absorbing and water-keeping super absorbent. |
| Keywords: | Carboxymethyl Cellulose Graft copolymerization Super absorbent resin of nitrogenous |
