Abstract

Abstract: The ESR spectra of magnanese sulfonated cthylene-propylene-diene terpolymer (SEPDM-Mn) in mixed solvent of xylene and alcohol have been investigated.The spectra exhibit resolved six hyperfine lines or a single broad line depending upon the solvation extent between Mn²⁺ and alcohol. The aggregation state of Mn²⁺ is affected by the coneentration of Mn²⁺, alcohol content in the mixed solvent,molecular volume of alcohol and temperature. All these results are consistent with those obtained from the viscometric behaviors of ionomer solutions

Key words: Ionomers, Sulfonated EPDM, Ionic interaction, Electron spin resonance
