Modified Nonconventional Synthesis of New Terpoly(Aniline, o-Anthranilic Acid and o-Phenylenediamine)/Bentonite Composites

Terpolymers of aniline, anthranilic acid and o-phenylenediamine/Hydrophilic bentonite composites were synthesized using a 1: 1: 1 molar ratio of the respective monomers with different percentages of clay via modified in situ chemical terpolymerization. The spectral characteristics upon incorporation of anthranilic acid units into the copoly(aniline o-phenylenediamine) backbone in absence and in presence of bentonite nanoparticles were investigated. Moreover, terpolymer/bentonite composites were thermally more stable than pure terpolymer under nonoxidative condition. On the basis of surface morphological studies of terpolymer composites, a platy network texture can be explained, and it can be clearly seen in the SEM photomicrographs.
