- Abstract
Motion of impurity ions in solid state of poly(ethylene telephthalate) (PET) was investigated by the method of broad band dielectric spectroscopy in a frequency range lower than 10 Hz. In this experiment, the conductivity relaxation time of the ion motion analyzed from the frequency dispersion of the electric modulus. The conductivity relaxation time for PET is evaluated at 0.53 at 100°C. This value is similar to those of low density polyethylene and poly(vinyl chloride) plasticized with dioctyl phthalate (p-PVC) but smaller than those of isotactic polypropylene. In a plot of conductivity relaxation time vs. permittivity, the location of PET is relatively nearby p-PVC. This result suggests that the inhomogeneity in non-crystalline part in PET is relatively similar to that of amorphous polymer of p-PVC rather than other polymers in this study.
