摘要：

Dielectric conductivity and permittivity of poly(ethylene glycol) were measured in the frequency range between 10(1) and 10(6) Hz during nonisothermal 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 serni-crystalline polymer.
