水的介电常数在添加聚（乙二醇）时急剧降低。该行为不是由线性混合方程描述的。降低的介电常数可导致膜结构的一般扰动，这是以膜的强聚集将导致其融合的方式所必需的。在聚乙二醇存在下的阳离子渗透性的变化可以解释为降低的介电常数对转移能量的影响。
The dielectric constant of water is reduced drastically on addition of poly(ethylene glycol). The behavior is not described by a linear mixture equation. The decreased dielectric constant can lead to the general perturbation of the membrane structure which is necessary in such a manner that a strong aggregation of membranes would lead to their fusion. The changed cation permeability in the presence of poly(ethylene glycol) can be explained as the effect of the lowered dielectric constant on the transfer energy.
