The present work involved preparation of new polyimides drived from chalcone derivative, chalcone compound prepared from reaction of ۴-amino acetophenone with vanillin, and then the chalcone which have amine group reacted with maleic anhydride to produce the corresponding amic acid. The synthesized amic acid compound was introduced in ring closure reaction by acetic anhydride and sodium acetate to produce maleimide. The new maleimdie was polymerized by free radical polymerization to yield homo and copolyimide with two vinylic monomers (acrylonitrile and methyl acrylate). The structures of synthesized compounds and polymers have been confirmed by physical properties and spectroscopy measurements (FT-IR) Fourier Transform Infrared Spectroscopy, (۱H-NMR) nuclear magnetic resonance. In addition, antibacterial activity of polymers was examined against two types of bacteria, namely Gram-negative and Gram-positive and gives good results in bacterial inhibition. Likewise, the anticorrosion activity of polymers was studied by using potensiostat measurements in acidic medium and the polymers give inhibition efficiency (۹۴%).
