摘要：

Dielectric measurements are made on samples of poly(ethylene terephthalate) (PET) during an isothermal crystallization process. At the initial stage of the crystallization the relaxation function, which is obtained from dielectric susceptibility, can be fitted by a stretched exponential function (KWW). As the crystallization proceeds, however, a deviation from the KWW equation is observed and the shape of dielectric loss versus frequency curve changes into a form described by the Cole-Cole equation.
