In the present paper, many unsaturated polyesters has been synthesized using maleic anhydride, phthalic anhydride and succinic anhydride for esterification with new monomer [E)-1-(4-hydroxyphenyl)-3-(3-methoxy-4-hydroxyphenyl) prop-2-en-1-one]. These polyesters were polymerized by condensation reaction . Their chemical structures were characterized using FTIR, 13C-NMR and 1H NMR spectroscopy. Thermal properties have been analysed using Differential Scanning Calorimetry of synthesized polyesters All the polymers showed well thermal stability and perfect data of glass transition temperature (Tg) also the results showed polyesters and monomer were successfully synthesized by giving well spectrum improved existing an ester functional group (-COO-) in spectrums each polymer prepared also existent Chalcone functional group(-CO-CH=CH-) in spectrum of monomer.
