Abstract

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

Author(s): 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
