Abstract

A law is proposed to link the evolution of the relaxation time τ with the temperature T in thermally stimulated depolarization current (TSDC) experiments (complex spectrum and elementary spectra). This model is equivalent to the classical one (compensation law) around T c. Its response, obtained by simulation of the complex and elementary spectra, is very close to the real depolarization current curves throughout the whole range of temperatures. Experimental results were obtained on an amorphous copolymer: PETN8 (92% of poly (ethylene terephthalate) (PET); 8% poly(ethylene naphthalene) (PEN).
