Synthesis and Characterization of Polymers Bearing Penicillinic Acid Moiety and Their Application

Abstract

    This work includes the preparation of a new monomer have an aminopenicillinic acid moiety and introducing in a homogeneous and co-polymerization reaction and studying the possibility of using them as corrosion inhibitors as well as studying some biological activity. Firstly amid acid was prepared from the reaction of 4-aminoacetophenone with maleic anhydride, then dehydration of water for ring closure of amic acid was performed to produce the corresponding imide, which in turn entered the Schiff base formation reaction with the aminopenicillinic acid compound to produce the required monomer , followed by the synthesis and preparation included conducting the polymerization process for the prepared monomer and preparing four new polymers (a homo polymer and three copolymers with vinyl monomers: acrylonitrile, methyl acrylonitrile, and methyl acrylate).Study of The biological activity of these polymers, as well as the study of the effectiveness of these polymers in protecting carbon steel from corrosion in an acidic medium, and the prepared polymers gave excellent results in both applications. Compounds and polymers prepared were identified by using techniques (FT-IR and 1H-NMR), spectroscopy, and study physical properties of compounds and polymers, including (melting points, softening points), and solubility.
