EPR of Mn2+, Fe3+ and Cu2+ in Ionomers,. aqueous solutions. Observations of Cu. dimers in carboxy telechelics and dry Flemion membranes are reported. These dimers have the same structure and the same physical properties as in the acetate salts.

Exafs Analysis of Ion Containing Polymers,t, the fully hydrated monovalent rubidium neutralized ionomers exhibited a highly disordered nearest-neighbor environment about the cation. It seems that a high degree of local structure about the cation is not necessary for the formation of ionic aggregates detected by small-angle x-ray scattering.

1389-2185 ing the past twenty years. The presence of ionic groups in the poly­ mer changes some of its properties dramatically. Increases in the modu­ lus and the viscosity of several orders of magnitude have been observed, and changes in the glass transition of hundreds of degrees are possible. In addition,

Chromium (III) and Cobalt (II) Aquo Complexes in PFSA (Nafion) Ionomer Films,I) complex results in both irreversible hydrolysis giving a hydroxo complex and reversible ligand substitution forming a chromium(III) aquo complex containing a sulfonate anion. The hexaaquo Co(II) complex does not undergo hydrolysis but can be reversibly dehydrated to form the novel Co(H.O).. tetrahedral complex.
