Abstract

Abstract

Polyethylene terephthtalate (PET) was depolymerized through aminolysis technique using ethanolamine into Bis (2-hydroxyethylene) terepthalamide (BHETA). BHETA is having hydroxyl functionality present in it so it is used as monomer and treated with sebacic acid using sulphuric acid as a catalyst. The synthesized resin having ester linkage present in it along with that in BHETA, amide linkage is also present hence it can be called as polyesteramide resin.  This synthesized carboxyl terminated resin was cured with epoxy in combination with Poly (o-anisidine) (POA) at various concentration of POA. Poly (o-anisidine) was investigated by Fourier Transform Infrared Spectroscopy, X-ray Analysis and Morphological Study. Coating shows excellent mechanical properties due to proper balance of flexibility and hardness. Anticorrosive properties of the coating were characterized by salt spray and Electrochemical Impedance Spectroscopy (EIS). Addition of POA helps to improve the anticorrosive properties of coating which was proved by salt spray and EIS.
