The aim of this study was to investigate the kinetic properties of hydrolyzed polyacrylamide gel. The hydrolyzed polyacrylamide was synthesized by free radical mechanism. The optimum molecular weight for the gel preparation was then obtained after examination of various factors such as average molecular weight, initiator concentration and reaction time in the gelation process. The main interaction which creates supramolecular gel is metal ligand coordination between carboxylate groups and chromium ions, and amide groups. These bonds were confirmed by FTIR and UV-Visible spectra techniques. Furthermore, the XRD showed crystalline structure in the gel.
