Synthesis of polymeric materials from natural renewable resources has attracted a lot of attention of researcher throughout the world as they not only reduce the dependency on petrochemicals but also friendly to the environment. Utilization of non-traditional and non-edible vegetable oils in the synthesis of valuable polymeric materials solves the problem of waste disposal as well as bringing down the cost of end products. Melia azedrach seed oil (MASO), a non-traditional and non-edible seed oil is utilized for the synthesis of poly(ester-amide) (MAPEA) by the aminolysis with diethanolamine followed by step-growth polymerization with phthalicacid. To improve the performances and utility of the MAPEA,methyl methacrylate (MMA) classified as hard monomer in the literature of acrylate embedded to it in different phr to obtained methyl methacrylate modified poly (ester-amide) (MMMAPEA) resins. The MMMAPEA resins were characterized by physic-chemical analysis as per standard reported methods. The structural elucidation of the resin was carried out by spectral analyses. Physico-mechanical and chemical/corrosion resistance performances of the MMMAPEA resins were investigated for the optimization of MMA content.
