The effects of dc conductivity and Maxwell-Wagner-Sillars (MWS) polarization on the dielectric behaviors of nylon 1010 have been investigated by means of dielectric relaxation spectroscopy. The experimental dielectric data were analyzed within the formalisms of dielectric permittivity, complex electric modulus, and complex impedance. The results were discussed in terms of dc conductivity, MWS polarization, electrode polarization, and conductivity relaxation. The results revealed that the charge carrier transport is governed by the motion of the polymer chains. There was a transition temperature located between 100 and 110 degrees C in the conductivity relaxation process, showing two different mechanisms for charge carrier movement. The change of charge carrier movement mechanisms was due to the motion of the polymeric chains in the interphase between amorphous and crystalline regions taking place at this temperature.
