Abstract: Polyethylene Terephthalate (PET) has been depolymerized by aminolysistechnique using ethanolamine to bis(2-hydroxyethyl) terephthalamide (BHETA). BHETA is a diol along with additional amide linkage as a structural part. It is used as hydroxyl precursor for the synthesis of polyetheramide resin. The conventional polyetheramide resin has been prepared by jatropha oil fatty acid amide and resorcinol. The modification is done in conventional resin with addition of BHETA by replacing fatty amide of oil on 50:50 molar basis. The synthesized resin was characterized by FTIR, 1HNMR and hydroxyl value. The synthesized resins are cured with Melamine Formaldehyde (MF) resin as a hardener and coating is prepared. The coating is evaluated for chemical, mechanical and anticorrosive properties. The anticorrosive performance of BHETA based polyetheramide is further improved by addition of polyaniline at various concentrations in coating system. 3wt% addition of polyaniline in BHETA based polyetheramide resin was shows best anticorrosive properties among all studied formulations.
