In this work, natural polymer Gelatin grafting was carried out with succinic anhydride by ring-opening polymerization then complexion with (Cr+3), (Mn+2), (Ni+2), and (Zn+2) was synthesized. The structure was characterized using FT-IR and UV-Vis. The results revealed that the structures of these complexes are Octahedral. The spectroscopic result of the ligand showed a bidentate behavior through the coordination via oxygen and nitrogen atoms. The newly synthesized polymers were tested as corrosion inhibitors on carbon steel alloy. The results of corrosion test indicated the corrosion decrease by using the new polymers on the service of the alloy. Inorganic polymers are appealing metals and alloys as corrosion inhibitors in various applications as they are cost-effective, renewable materials that are readily accessible, non-hazardous, possibly biodegradable, and biocompatible with the natural environment.
