✦ Synopsis

Conducting crystalline polyazomethine polymers with high solubility and low melting points have been prepared and studied. The polymers were synthesized by the polycondensation of p-phenylene diamine and 2-nitro-pphenylene diamine with terephthaldehyde and p-diacetylbenzene. Polymers with polar functional groups and methyl side groups were found to be more NO 2 soluble in common organic solvents and to possess lower melting points. The polymers were studied using IR and UVÈvisible spectra, elemental analyses, solubility, inherent viscosity, X-ray di †raction, scanning electron microscopy and d.c. electrical conductivity.
