Abstract
A continuous process for sulfonating elastomeric polymers to form neutralized sulfonated elastomeric polymers with improved physical properties includes the steps of; (a) contacting a cement of an elastomeric polymer with a sulfonating agent in a staged reaction vessel for a sufficient period of time at a temperature of about -50.degree. C. to about +100.degree. C. to form an unneutralized sulfonated elastomeric polymer; (b) continuously transferring the cement of the unneutralized sulfonated elastomeric polymer to a neutralization vessel; (c) continuously adding a quenching agent and neutralizing agent to the cement of the unneutralized sulfonated elastomeric polymer in a staged neutralization vessel wherein the sulfonated cement is quenched and the neutralization agent reacts with the unneutralized sulfonated polymer to form the neutralized sulfonated elastomeric polymer; and (d) isolating said neutralized sulfonated elastomeric polymer.
