Abstract: Vegetable oils are excellent source of raw material for the development of low molecular weight polymers for protective applications. Pongamia glabra oil is non-edible and non-drying in nature and has found application in the field of medicine, leather tanning, soap industry, biodiesel and polymeric materials. An efficient synthesis of Pongamia glabra polyesteramide has been achieved using microwave irradiations without harmful organic solvent for their commercialization. Pongamia glabra polyesteramide steps of the process both amination of oil (obtained diol fatty amide) and esterification of diol fatty amide (obtained polyesteramide) were carried out under microwave irradiations. It allowed reducing the reaction time of both aminolysis and esterification steps in comparison to the same process carried out under conventional thermal conventions. The polymer sample was tested for their chemical as well as mechanical properties. The structure of the polymer has been supported by their spectral data (FTIR, 1H NMR and 13C NMR techniques).
