Abstract

Abstract: The ionic interaction in ionomer solution of manganese sulfonated EPDMhas been investigated by viscometric method, as well as FTIRand ESRmethods.The results indicate there exists sol-vation between Mn²⁺ and alcohol cosolvent, the extent of which depends upon the concentration of Mn²⁺, alcohol content in the mixed solvent, molecular volume of alcohol and temperature.All these factors affect the aggregation state of Mn²⁺ in solution and the ionic interaction between the solvated Mn²⁺ and sulfonate anion SO₃^- in the ionomer macromolecule.

Key words: lonomer, Viscometric behavior in solution, Infrared spectrum, Electron spin resonance
