Summary, etc. The refractive index (<em>n</em>), dispersion and optical conductivity (σ<sub>opt</sub>) of undoped and PPy doped PVC films have been studied. The PPy doped PVC films   are prepared by solution cast technique with various concentrations of PPy (6% to 20%) in PVC. The optical absorption spectra of these films have been recorded in the wavelength range 400-900 nm at room temperature. Optical parameters such as refractive index (<em>n</em>), extinction coefficient (<em>k</em>), real (εʹ) and imaginary (εʹʹ) parts of complex permittivity, optical conductivity (σ<sub>opt</sub>) and infinitely high frequency dielectric constant (ε<sub>∞</sub>) have been evaluated. It is seen that the optical properties of PVC have been affected on doping it with PPy. The average refractive index (<em>n</em>), infinitely high frequency dielectric constant (ε<sub>∞</sub>) and optical conductivity (σ<sub>opt</sub>) of the samples exhibit a nonlinear compositional dependence as observed in many amorphous materials.
