AbstractThe AC conductivity and the dielectric properties were measured as a function of temperature and frequency for the pure and blended chlorinated polyvinyl chloride (CPVC) polymer samples. The DC conductivity was measured in the same range of temperature. The effect of metal ion concentration as well as its ionic radius on the above properties was studied. The measurements of conductivity showed the existence of more than one conduction mechanism. Both DC and AC conductivities increase with increasing the metal ion content. The obtained values of the activation energy indicate the semi conducting behaviour for metal-doped samples. © 2005 IACS.
