Synthesis, characterization and thermal stability of poly (azomethine) esters containing different linkage groups

Pooja Sharma, A.K.Narula

This paper describes the synthesis of polyesters with azomethine groups by the reaction of dihydroxymonomerswith other linkage groups (-PO- / -S-) between phenylene rings with diacids [naphthalene 2,6-dicarboxylic acid (NDA), cyclobutane1,2-dicarboxylic acid (CDA) and 3,3Â’-bisphenyldicarboxylic acid (BDA)] have been prepared. The characterization of synthesized polyesters was done by using FTIR and 1H-NMR spectroscopic techniques. Their thermal stability has been studied by thermogravimetric analysis
