Abstract :
Dielectric conductivity and permittivity of poly(ethylene glycol) were measured in the frequency range between 101 and 106 Hz during non-isothermal crystallization and melting with different cooling/heating rates (5, 10 and 20 K/h). The time development of the conductivity and permittivity spectra during crystallization and melting is discussed in terms of charge carrier diffusion in a percolation network formed by the amorphous phase of the semi-crystalline polymer.
