ABSTRACT:
This invention relates to an improved process for the manufacture of a blend composition of a neutralized sulfonated elastomeric polymer which includes the steps of sulfonating an elastomeric polymer dissolved in a solvent to form an acid form of the sulfonated elastomeric polymer. The solution of the acid form of the sulfonated elastomeric polymer is quenched with an oxirane to form a polymeric hydroxyalkyl sulfonate. A non-polar backbone process oil is added thereby plasticizing the polymeric backbone of the hydroxyalkyl sulfonate. The hydroxyalkyl sulfonate is reacted with a metal carboxylate to form equal molar portions of a solid gel-free neutralized sulfonated elastomeric polymer and a hydroxyalkyl carboxylate ester.
