  In this study, first copolymer (methyl methacrylate-maleic anhydride) was synthesized and then it reacted with different amount of hydrazine hydrate. Primary copolymers and products were detected by Fourier transform infrared spectroscopy and nuclear magnetic resonance (NMR), the glass refractive temperatures (Tg) were determined by thermal decomposition (TGA-DSC). The results showed that copolymerization of methyl methacrylate with maleic anhydride increased the thermal stability of the polymer compared to poly (methyl methacrylate) also addition of hydrazine improved the thermal stability of the copolymer. The percentage of elements in the copolymer reacted with hydrazine was determined using elemental analysis (CHNS) and their transparency with the spectrum of light transmission in the visible-ultraviolet region showed that although copolymerization reduced the transparency and light transmission in the visible region but Increasing hydrazine not only solves this problem but also makes the product more transparent than poly PMMA. Also Solutions with concentrations of 50 to 200 ppm of primary copolymer and two of the products were prepared and theirs inhibitory performance on corrosion of low carbon steel in 0.05 M hydrochloric acid (HCl) solution was investigated using potentiodynamic polarization, X-ray energy scattering analysis (EDX) and weight loss methods. The results confirm the increased corrosion inhibitory power of the copolymer in acidic environment. Manuscript profile
