SYNTHESIS AND CHARACTERIZATION OF CERTAIN POLYESTER AMIDES

The introduction of amino phenol unit in polymeric chain enhances the desired properties such as increase in thermal and mechanical properties of polyester amides which finds diverse applications. In this paper, we report on synthesis of polyester amide by condensation method using two different bifunctional symmetric monomer units of amino phenol (OAP and MAP) with acid chloride (TPCl) in presence of cetyltrimethyl ammonium bromide phase transfer as catalyst. The repeating unit of the synthesized polyester amide has been determined by fourier transform infrared spectroscopy (FTIR) and H1 proton nuclear magnetic resonance (1HNMR), 13C nuclear magnetic resonance (13CNMR) spectral method. The morphology of the synthesized polyesteramide was studied using SEM. The polymer PEAs indicates that the melting temperature (Tm) based on differential scanning calorimetry (DSC) analysis
