| Abstract: | The graft copolymer of potato starch and acrylonitrile was prepared with eerie ammonium sulfate as initiator and in the presence of the formaldehyde, Water-absorbable resin of correcting property by formaldehyde was prepared with saponification of the graft copolymer .The relations of the water-absorption rate of the resin, with the weights of formaldehyde, acrylonitrile, water of the starch pasting and alkali of the saponif ication and the reaction temperatures and times were studied. The experiment shows that the super water-absorbable resin has pretty good water-absorption rate. |
