Abstract: The instant invention relates to a method for making processable ionic polymer compositions which are characterized as being processable at high temperatures, for example, 200.degree. C, while retaining adequate physical properties at both room temperatures and elevated temperatures which are below the processing temperature, for example, up to 100.degree. C and more. In this method, an ionic polymer comprising an elastomeric or plastic backbone and pendant acid groups is combined with a first neutralizing agent having two components. One component of said neutralizing agent is a metal or ammonium type moiety which combines with the pendant acid groups as a metal or ammonium salt thereof; the other component of neutralizing agent takes up the hydrogen ion present in the pendant acid groups and is converted into a preferential plasticizer for said ionomer.
