摘要：

The interaction of several plasticizers with the zinc cation in zinc-neutralized sulfonated polystyrene was examined with extended x-ray absorption fine structure (EXAFS) spectroscopy. Glycerol and water were found to interact strongly with the zinc cation, plasticizing the ionic aggregates. At full solvation by glycerol, the zinc atom was found to be coordinated by three glycerol molecules. Dioctylphthalate, acetonitrile, and toluene, which are unable to coordinate to the zinc cation, were found to have a minimal effect on the cation's local structure.
