Abstract
This invention relates to an improved elastomeric composition of metal and ammonium neutralized sulfonated elastomeric polymers which are preferentially plasticized with an organic urea or organic thiourea at a minimum critical concentration level of at least 5 parts by weight based on 100 parts by weight of the metal neutralized elastomeric polymer, wherein the plasticized compositions have an improved balance of physical and rheological properties. These elastomeric compositions can be readily processed due to their superior rheological properties on conventional plastic fabrication equipment.
