Abstract
The synthesis and characterization of aromatic oligo(azomethines) hybrids by thermal oligomerization of a new monomers is reported. The new oligo(azomethines) have been characterized using, FT-IR, 1H-NMR and 13C-NMR spectroscopy, elemental analysis, thermo gravimetric and viscosimetric measurements. These oligomers were synthesized by the intermolecular reaction between the ester group and the amine group, and the resulting products contain simultaneously imine, amide and carboxylic acid groups. The soluble oligomers were fractionated and it was possible to obtain a materials of different solubility and molecular size. The oligomers have high thermal stability that reached a loss of mass even of 10% at 460 °C.
