    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 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.

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.

    摘要: A bulk sulfonation process for the preparation of sulfonated polymers from hydrocarbon polymers having olefinic unsaturation or aromatic moieties, or both, includes intimately mixing the polymer by mechanical means in the absence of a solvent for the polymers with a sulfonation reagent at a sufficient temperature and time to effect the desired degree of sulfonation. The sulfonated polymer may be recovered as the free sulfonic acid or neutralized ionically with a basic compound. Sulfonated polymers including a substantial proportion of aromatic moieties yield water-soluble or water-dispersible salts, useful as thickening and flocculating agents, when neutralized with ammonia monobasic cations or lower alkyl amines. These materials, however, when sulfonated at a low level, e.g.

    摘要: This invention relates to processable ionic elastomer compositions having improved compression set properties, especially at elevated temperatures. In this invention an intractable ionic elastomer, for example, a sulfonated elastomer is blended with from 10 to 70 parts per hundred of a crystalline polyolefin to yield novel compositions having the above properties. Preferably the ionic elastomer is a sulfonated ethylene propylene terpolymer having from about 0.2 to 20 mole percent sulfonate groups, at least 95% of which are combined with counterions selected from the group consisting of Groups IA, IIA, IB, and IIB of the Periodic Table of Elements, aluminum, antimony, lead, and mixtures thereof. The sulfonated polymer is combined with said counterions by neutralization of a polysulfonic acid precurser with a basic material in which the desired counterion is present as the cation thereof. The anion of said basic material is preferably selected from the group consisting of oxide, hydroxide, and lower alkanoates, for example, acetate, formate, and propionate.

    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 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.
