In this paper, A n ovel superabsorbent nanocomposite based on pectin has b een prepare d via graft copolymerization of acrylic monomers in the presence of montmorolonite clay powder. Evidence of grafting and montmorolonite interactio n was obtai ned by comparison of FTIR, TGA and DSC sp ectra of the i nitial substrates and the superabsor bent nanocomposite.
