Organic solvent free microwave synthesis of <i>Pongamia glabra </i>oil based polyesteramide

Abstract

Vegetable oils are excellent source of raw material for the development of low molecular weight polymers for

protective applications. <i>Pongamia glabra </i>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 <i>Pongamia</i>

<i>glabra </i>polyesteramide has been achieved using microwave irradiations without harmful organic solvent for their

commercialization. <i>Pongamia glabra </i>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).
