Abstract
The four isomeric Schiff base polymers, poly(p-xylylidene-p-phenylenedi-amine), poly(p-xylylidene-m-phenylenediamine), poly(m-xylylidene-p-phenylenediamine), and poly(m-xylylidene-m-phenylenediamine) were synthesized by the bis-Schiff base exchange reaction from the appropriate pairs selected from the four monomers, N, N'-bisbenzylidene-p-phenyl-enediamine, N, N'-bisbenzylidene-m-phenylenediamine, p-xylylidenedianil, and m-xylylidenedianil. The differences in the thermal stabilities in nitrogen and in air of these four isomeric polymers prepared by condensation to temperatures of 400 and 600°C are minor.
