✦ Synopsis

FTIR and ESR studies of sulfonated EPDM ionomers in xylenejalcohol show that alcohol solvation of -SOBM occurs and the extent of solvation relates to the species and concentration of the metallic ions and the molar concentration of -OH from the cosolvent (alcohol) and temperature. The relationship between these factors and the viscometric behaviors of the ionomer solution were investigated. The results of these two studies are quite consistent with each other. At the molecular level the solvation of the metallic ion with the cosolvent plays a key role in the anomalous viscosity-temperature behavior of ionomer solutions.

Raman spectroscopy was used as a complementary tool to thermal and x-ray methods in phase equilibrium studies of the NaNO 3 -KNO 3 system. Based on the microscopic structures of the system, the Raman technique confirned the phase diagrams obtained by thermal studies. Structural phase transitions of
