Chemical Synthesis, Spectral Characterization and Thermal Degradation of Poly (aniline-co-m-chloroaniline)

Copolymers of aniline with m-chloroaniline were synthesized for different molar ratios of the respective monomers in acid medium. The structural properties of these co-polymers were characterized by using FT-IR and UV-VIS spectroscopic methods. The electrical conductivity was measured by two probe method. It was found that the conductivity of these co-polymers decreases with increase of the chloroaniline content in the copolymerization reaction. Temperature dependence of electrical conductivity data was discussed in terms of Arrhenius and variable range hopping model to elucidate the conduction mechanism. The thermal degradation of these polymers was analyzed using thermo gravimetric analysis.
