Description
Summary:An interpretation by mathematical theory of experimental data already published by the author is given, concerning the electrical conductivity measurement, in direct current, of PVC and plasticizer compositions. The electrical conduction in PVC is due to two mechanisms: one of polarization, which predominates at low temperature, below a transition temperature T 0 and one of ionic conduction which predominates at high temperature above T 0. The mathematical expressions for polarization conductivity k p and ionic conductivity k 0, agree very well with the experimental data and justify also the great difference in activation energy between the two mechanisms and the independence of activation energy of ionic conductivity from the system viscosity and type of ions.
