使用扩展 X 射线吸收精细结构 (EXAFS) 测量来确定几种离聚物系统中中和阳离子的近邻环境。将观察到的结构与类似的低分子量结晶盐中存在的结构进行比较。尽管所有系统都表现出相似的小角度 X 射线散射曲线，表明离子微域的存在，但在不同系统之间观察到局部有序程度存在很大差异。
Extended x-ray absorption fine-structure (EXAFS) measurements were used to determine the near-neighbor environment of the neutralizing cation in several ionomer system. The observed structure is compared to that existing in analogous low-molecular-weight crystalline salts. A wide variety in the degree of local order was observed between different systems even though all exhibit similar small-angle x-ray scattering curves indicating the existence of ionic microdomains.
