ABSTRACT: The present work reports the oxidative synthesis of poly aniline using K2Cr2O7 as an oxidizing agent and H2SO4 as dopant. The synthesized polymer was characterized by solubility test and UV-visible spectroscopic technique. The synthesized polymer (poly aniline) was insoluble in ethanol, acetone, benzene and water. The absorbance of UV-visible spectra shows two reductive peaks at some wake length. The band observed at 327 - 365 nm for the PANI samples corresponds to n-p* transitions of aniline and the broad band at 600 - 620 nm is due to n-p* transitions of quinineimine groups.
