	The present work reports the oxidative synthesis of poly aniline using K<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub> as an oxidizing agent and H<sub>2</sub>SO<sub>4</sub> 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<sup>*</sup> transitions of aniline and the
broad band at 600 - 620 nm is due to n-p<sup>*</sup> transitions of quinine-im-
ine groups.
