ABSTRACT: Biosuperabsorbent polymers are obtained by the graft copolymerization of acrylic acid (AcA) and acrylonitrile(AN) monomers onto CMC, using Ceric ammonium nitrate as a free radical initiator in the presence of methylene bisacrylamide as a crosslinker. Infrared spectroscopy and TGA thermal analysis were carried out to confirm the chemical structure of the hydrogel. Moreover, morphology of the samples was examined by scanning electron microscopy (SEM). Final, The swelling kinetics of the synthesized hydrogels with various particle sizes was also preliminarily investigated.
