  • Patent number: 4277381
    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.

  • Patent number: 4222914
    Abstract: This invention relates to a process for the formation of a neutralized sulfonated polymer having about 10 to about 60 meq. sulfonate groups, wherein the sulfonate groups are neutralized with a zinc counterion. A cement of a polymer having olefinic functional groups and a non-reactive solvent is contacted with a sulfonated agent such as an acyl sulfate. The sulfonated polymer is then neutralized with a solution of zinc acetate dissolved in a solvent system of methanol alone or methanol and water, wherein the volume percent of methanol based on non-reactive solvent is less than about 10. A carboxylic acid can be then added to the cement of the neutralized sulfonated polymer thereby forming a zinc salt of the carboxylic acid in situ, wherein the zinc salt of the carboxylic acid is a preferential plasticizer for the zinc sulfonate groups. The Brookfield viscosity at 0.6 rpm at room temperature of the cement of the zinc neutralized sulfonated polymer is less than about 50,000 cps.
