Superabsorbent polymers were prepared using acrylonitrile grafted to corn starch employing low levels of gamma ray radiation as initiator. Various grafting parameters have been studied at these low dosages. Absorbency values for the final products are reported. Use of the above superabsorbent as a desiccant has been evaluated. The product will find application where dispersions of low viscosity and high water absorbencies are desired.
