Dielectric relaxation in poly(2-ethynylnaphtalene) determined by thermally stimulated depolarization currents

Summary

The thermally stimulated depolarization currents from poly(2-ethynylnaphtalene) with cis-cisoidal and transcisoidal structures were studied over the temperature range 200–380 K. The single peak ρ of the cis-cisoidal isomer was assigned to the Maxwell-Wagner polarization. The β1 and β2 peaks of the trans-cisoidal isomer arise from a single dipolar relaxation process and respectively from a dipolar relaxation distributed in natural frequency. Certains assignements are based on comparative work on polyphenylacetylene.
