ABSTRACT:
This invention relates to a process for the manufacture of a blend composition of a neutralized sulfonated ethylene propylene terpolymer (EPDM) which includes the steps of sulfonating the EPDM dissolved in a solvent to form an unneutralized sulfonated elastomeric polymer. The solution of the unneutralized sulfonated EPDM is quenched with an aliphatic alcohol. The unneutralized sulfonated elastomeric polymer in solution is then neutralized with a neutralizing agent to form the neutralized sulfonated EPDM in solution. A critically selected non-polar backbone process oil is added under agitation to the solution thereby plasticizing the neutralized sulfonated EPDM with the process oil. The neutralized sulfonated EPDM plasticized with the process oil is then recovered from the solution.
