AbstractExtended x-ray absorption fine structure (EXAFS) spectroscopy has beensuccessfully applied to the analysis of the ionic domain microstructure inzinc and rubidium neutralized ionomers. In dehydrated zinc neutralizedionomers, the zinc cation was found to be tetrahedrally coordinated to oxygenatoms. For ionomers with hydrocarbon backbones, these oxygen atoms mayoriginate from the sulfonate or carboxylate groups. For ionomers withperfluorinated backbones, some of the oxygen atoms may be ascribed to watercoordination as well. In fully hydrated zinc neutralized ionomers, thezinc cation exists as Zn( H2O)62+. In contrast, the fully hydrated monovalentrubidium neutralized ionomers exhibited a highly disordered environmentabout the cation.
