Abstract
This invention relates to improved elastomeric compositions of metal and ammonium neutralized sulfonated elastomeric polymers which are preferentially plasticized with a naphthalene amide at a minimum critical concentration level of at least 8 parts by weight per 100 parts of the metal neutralized elastomeric polymer, wherein the composition has an improved balance of physical and rheological properties, especially at elevated use temperatures. These compositions can be readily processed due to their superior rheological properties on conventional plastic fabrication equipment.
