Results of dielectric relaxation studies will be discussed. It turns out that competition of electric and structural relaxation coins permittivity and as a result conductivity mechanism at low temperature. It dominates long-ranging relaxation in the molten state. In the opposite limit of temperature, cross-linked poly(ethylene oxide) (PEO) with low mesh size can be transferred into super-cooled liquid state. Then, PEO behaves like a hydrogen-bonded liquid since crystallization is strongly suppressed. As a result, one observes slow Debye-like relaxation at low temperature. Beyond the low-frequency region, there appears an extended region between crossings of impedance components, where Z′ ≈ Z″ at acceptable approximation. It is coined by damped oscillation under action of the electric field. These effects lessen with increasing mesh size of the sample as clearly shown by M″(ω) spectra. The dipole moment of the PEO samples in molten state decreases only slightly with increasing mesh size.

将讨论介电弛豫研究的结果。事实证明，电和结构弛豫的竞争决定了低温下的介电常数和导电机制。它在熔融状态下主导长程弛豫。在相反的温度限制下，具有低网目尺寸的交联聚（环氧乙烷）（PEO）可以转变为过冷液态。然后，由于结晶受到强烈抑制，PEO 表现得像氢键液体。结果，人们在低温下观察到缓慢的德拜式弛豫。在低频区域之外，在阻抗分量的交叉点之间出现了一个扩展区域，其中Z ′ ≈  Z”在可接受的近似值。它是由电场作用下的阻尼振荡创造的。这些影响随着样品网格尺寸的增加而减弱，如M ''( ω ) 光谱所示。熔融态 PEO 样品的偶极矩随着网格尺寸的增加仅略微降低。
