%X The nature of the MnCl<sub>2</sub>  salt as a filler to polycarbonate , including their composition, particles dimensions and homogeneity of distribution have been studied using different spectroscopic techniques (XRD, DSC and TGA). A  slight increases in  the chain-chain separation due to the interaction  of the MnCl<sub>2</sub> salt with the polycarbonate chains was observed , while a decrease in the optical energy gap (E<sub>opt</sub> ) of the polycarbonate polymer with increasing the salt concentration was detected .However employing impedance spectroscopy in the frequency range 10Hz up to 10<sup>6</sup> Hz. reveals an increase in  the dielectric permittivity and conductivity with increasing salt content
