Synthesis and properties of poly(o-phenylenediamine)

Poly(o-phenylenediamine) has been prepared under different polymerization conditions in nitrogen atmosphere using chemical and electrochemical methods. The effect of current density, reaction temperature and the nature of solvents on polymer yields and polymer conductivities has been investigated. The cyclic voltammogram of o-phenylenediamine was examined in the range 0.0 to 1.0 V vs SCE in aqueous solution of hydrochloric acid. Morphological property of the polymer was obtained by scanning electron micrograph (SEM). These polymers are found to have electrical conductivity in the range of 10(-9) to 10(-7) S cm(-1). Magnetic susceptibility of polymer sample was also determined.
