ABSTRACT
Copolymers of o-anthranilic acid and o-phenylenediamine/hydrophilic bentonite nanocomposites were synthesized by 1:1 molar ratios of the respective monomers with different percentages of nanoclay through modified in situ chemical copolymerization. The results obtained were justified by measuring the Fourier transform infrared of poly(o-anthranilic acid-co-o-phenylenediamine) emeraldine base/bentonite nanocomposites. Ultraviolet–visible spectra of poly(o-anthranilic acid-co-o-phenylenediamine) emeraldine base/bentonite nanocomposites were investigated. The thermal stability was studied, and it was found that poly(o-anthranilic acid-co-o-phenylenediamine) emeraldine base/bentonite nanocomposites were thermally more stable than pure copolymer. X-ray diffraction patterns of copolymer poly(o-anthranilic acid-co-o-phenylenediamine) emeraldine base and poly(o-anthranilic acid-co-o-phenylenediamine) emeraldine base/bentonite nanocomposites were studied.
