    摘要： Adhesive contact cements of sulfonated olefinically unsaturated elastomers (sulfobutyl rubber) containing from about 0.1 to about 5.0 mol % SO3H 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.

    摘要： Sulfonated butyl rubber containing greater than 0.5 mole percent sulfonate functionality is emulsified by dissolving the butyl rubber in an aromatic solvent, i.e. toluene, sulfonating the polymer, neutralizing the polymer with a weak base, and thereafter emulsifying the solution using as the emulsifying agent an anionic emulsifier, i.e. a sodium sulfate derivative of an ethoxylated nonyl phenol containing 4 moles of ethylene oxide.
