摘要： 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.

摘要： This invention relates to a process for first preparing a free flowing finely divided powder of a neutralized sulfonated elastomer and subsequently and optionally admixing said formed powder with other agents such as fillers and oils thereby providing free flowing powders capable of being subsequently fabricated into tough elastomeric objects. The neutralized sulfonated elastomeric polymer can be converted into a free flowing finely divided powder which does not agglomerate or cold flow under ambient conditions by a variety of processes, preferably by a grinding process conducted at low temperatures. The formed powder of the neutralized sulfonated elastomeric polymer is blended with at least one chemical additive into a homogeneous mixture, wherein the chemical additive is selected from the group including fillers, polyolefinic thermoplastics, non-polar backbone process oils, lubricants or a metallic oxide and mixtures thereof. The homogeneous mixture is formed into a finished elastomeric article by conventional fabrication.

摘要： This invention relates to an improved process for the formation of an improved gel-free neutralized sulfonated elastomeric polymer having about 10 to about 50 meq. unneutralized sulfonate groups, wherein the unneutralized sulfonate groups are neutralized with a metal counterion being selected from the group including lithium, sodium, potassium, cesium, barium, calcium, magnesium, zinc, lead, iron (II), copper (II), mercury (II), and nickel. A cement of an elastomeric polymer having olefinic functional groups dissolved in a non-reactive solvent is contacted with a sulfonating agent such as an acyl sulfate thereby sulfonating the elastomeric polymer, and the sulfonation reaction is subsequently quenched by the addition of isopropanol at a concentration level of about 5 to about 30 volume percent based on a volume of the non-reactive solvent. The unneutralized sulfonated elastomeric polymer is then neutralized with a neutralizing agent dissolved in water, the water being at a concentration level of less than about 2.5 volume percent based on the volume of the non-reactive solvent thereby forming a gel-free cement of the neutralized sulfonated elastomeric polymer having a Brookfield viscosity at room temperature of less than about 20,000 cps.
