Hydroxamated poly acrylamide (HPAAM) was prepared by coupling reaction of polyacrylamide (PAAm) and free hydroxylamine in alkaline solution (pH>12) at 70˚C. The synthesized HPAAM was characterized by CHN elemental analysis, Fourier-transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (¹HNMR) and thermogravimetric analysis (TGA). CHN elemental results have demonstrated that HPAAM composes of 29.71% carbon, 4.08% hydrogen and 12.66% nitrogen. Characteristics absorption bands of HPAAM functional groups at 3300-3600cm^-1 (OH), 1666 cm^-1 (C=O) and (N-H) 3211 cm^-1 were noticed from FTIR spectrum. Furthermore, ¹HNMR has shown the disappearance of the olefenic protons and the presence of the characteristics signals of methylene and methyne of the main chain of the PAAm at 2.3-2.8 ppm and 3.2-3.7 ppm respectively. TGA thermogram of HPAAM has shown three characteristics mass loss and it was less thermally stable than PAAm.
