This work was aimed to prepare new monomer (E)-1-(4-aminophenyl)-3-(4-hydroxyphenyl) prop-2-en-1-one] and three types of poly (ester-amide) polymers. New monomer is Chalcone compound α,βunsaturated ketone contain functional group(-CO-CH=CH-) of presence system α,βunsaturated carbonyl group. It is prepared by condensation aryl ketone with aromatic aldehyde with presence of suitable condensation agents which called Aldol condensation. Monomer reacted with (phthalic anhydride maleic anhydride salicylic acid and succinic anhydride) Via solution poly condensation reactions to yield three types of polymers. The prepared monmer and polymers were characterized by [(FT.IR-spectra, Nuclear magnetic resonance 1H.NMR-spectra , 13C.NMRspectra and Differential scanning calorimetry (DSC)] All the polymers showed good thermal stability and good data of glass transition temperature (Tg). The results revealed that poly (ester-amide)s were successfully prepared by giving good spectrum which improved the existed amide functional group (-CONH-) and ester functional group (-COO-) in spectrum of each prepared polymer, furthermore the existed chalcone functional group(-CO-CH=CH-) is improved in spectrums of monomer.

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.
