    摘要: A process for sulfonating unsaturated elastomers which comprises sulfonating an olefinically unsaturated elastomer using as the sulfonating agent an acyl sulfate. The products produced thereby have improved properties over those sulfonated elastomers prepared by prior art methods. The preferred acyl sulfate is acetyl sulfate. The sulfonated elastomers of this invention are useful as films, adhesives and for other general purpose rubber uses. Especially advantageous properties are obtained when the sulfonic acid polymer is neutralized with ethylamine.

    摘要: A process for sulfonating polymers which are prepared by solution polymerization using a Friedel-Crafts or Ziegler-type catalyst is disclosed. The reactor effluent containing polymer, unreacted light monomers, diluent-solvent and active catalyst is first treated to remove substantially all unreacted light monomer, e.g. by flashing. The effluent is then treated with a sulfonating agent (e.g. acetyl sulfate and acetic acid) which simultaneously deactivates catalyst. Thereafter, the sulfonated polymer is neutralized, e.g. by exposure to metal salts, organic amines, etc., and subjected to normal finishing operations, e.g. deashing, steam stripping, stabilizing and drying.

    摘要: Polymers having one or more sulfonic acid groups covalently bonded to one or more carbon atoms including the polymer are stabilized against thermal and hydrolytic degradation by reaction with an oxirane. The solid, gel-free hydroxyalkyl sulfonates thus formed are readily converted to thermoplastic ionomers by reaction with a metallic base or salt of a weak acid. The polymeric hydroxy alkylsulfonates possess a low melt viscosity and thus are readily mixed with neutralizing agents, plasticizers or other polymers and thereafter converted to ionomers by reaction with the neutralizing agent which is a metallic base or salt of a weak acid. The formulated solid gel-free ionomers are thermoelastic in nature and can be extruded, injected molded, and compression molded to useful products.

    摘要: This invention relates to moldable or extrudable type elastomeric compositions having a viscosity at 200.degree. C at 0.73 sec.sup.-1 of about less than about 10.sup.5 poise. The compositions used for elastomeric articles include 100 parts of a neutralized sulfonated EPDM terpolymer; about 25 to about 150 parts per hundred of a non-polar process oil; about 25 to about 200 parts per hundred of a filler; and about 2 to about 50 parts of a hydroxyalkyl carboxylate ester.These blend compositions can be readily processed due to their superior rheological properties on conventional plastic fabrication equipment into elastomeric articles having excellent physical properties and desirable rubbery characteristics.

    摘要: Adhesive contact cements of sulfonated olefinically unsaturated elastomers (sulfobutyl rubber) containing from about 0.1 to about 5.0 mol % SO.sub.3 H neutralized, partially neutralized, or unneutralized, are admixed with tackifiers, i.e. phenolformaldehyde resins, polyisobutylene, alkylphenol formaldehyde resins, petroleum resins, etc. in an amount of between about 5 and about 90 phr in between about 10 and about 50 wt. % solids concentration in organic solvents. These cements are used for adhering porous or non-porous materials such as textiles, wood, cloth, sheets or strip of metals, plastics, etc. to each other. High green strength, high tensile strength, high resistance to peel, even at elevated temperatures, water impermeability, etc. characterize such adhesive layers in laminates. A preferred solvent, 90% toluene, 10% isopropyl alcohol is used in compounding the cement and preferably an organic amine, e.g. ethylamine, is used to partially or completely neutralize the sulfonated elastomer although inorganic bases may also be used for neutralization.
