Abstract: A dyeable olefinic polymer composition comprising an olefinic polymer, and the reaction product of 50 to 90% by weight of the full nickel phenolate of o,o'-bis(p-1,1,3,3-tetramethylbutylphenol)sulfone and 50 to 10% by weight of a secondary or tertiary organic phosphite.

Abstract: An improved process for the sulfonation of an unsaturated elastomeric polymer to form a sulfonated elastomeric polymer, wherein a cement which contains an elastomeric polymer dissolved in a non-reactive solvent is contacted with a sulfonating agent at between about -100.degree. C. and +100.degree. C. for a period of time sufficient to result in the sulfonation of the elastomeric polymer wherein the improvement includes the use of a sulfonating agent which is formed from mixtures of a sulfur trioxide donor complexed with a Lewis base and a carboxylic acid anhydride ##STR1## or an acyl halide ##STR2## or with both, wherein R is selected from the group consisting of CH.sub.3 --, C.sub.2 H.sub.5 --, C.sub.3 H.sub.7 --, C.sub.4 H.sub.9 --, C.sub.5 H.sub.11, C.sub.6 H.sub.13 and C.sub.6 H.sub.5 and mixtures thereof. The molar ratio of ##STR3## and/or ##STR4## with the SO.sub.3 of the complex is at least 0.5.

Abstract: This invention relates to a novel elastomeric foamed material which has surprisingly been found to exhibit a variety of unusual and desirable features both in its physical properties and in its process of manufacture. These foamed compositions of a lightly sulfonated elastomeric gum contain a nonvolatile polar plasticizer and preferably extenders such as oil and fillers. These elastomer foams exhibit an unusual profile of physical properties including melt reprocessability of fabricated articles, and high temperature reshaping of foamed objects while maintaining a good foam structure. These novel foams can be manufactured with relatively uniform cell structures and with small cell sizes at foam densities from near bulk density to less than 0.1 g/cc.

Abstract: Sulfone-crosslinked polystyrene cation and anion exchange resins having high solids content when saturated with water are disclosed together with a method of forming increased amounts of sulfone crosslinks using a sulfonating agent or mixture thereof preferably in combination with a boron compound.

Abstract: Ionomers comprising higher alkyl ammonium or quaternary polyammonium salts of polyacids, particularly sulfonic acids, having anionic groups covalently bonded to carbon atoms comprising a backbone chain of a polymer, or to acyclic, alicyclic or aromatic radicals which are pendant to the backbone chain of the polymer, are novel compositions of matter. These ionomers vary in properties from water-soluble polyelectrolytes useful as thickening agents to thermoplastic elastomers which can be extruded, injection molded, vacuum formed, etc. at elevated temperatures. The elastomers are useful as specialty and general purpose rubbers.

Abstract: This patent relates to thermoplastic blend compositions having improved stiffness and increased glass transition temperature, wherein a major portion of polar thermoplastic resin is compounded with a minor portion of a neutralized sulfonated polymer. The neutralized sulfonated polymers of the present invention included sulfonated polystyrene butadiene copolymers, sulfonated butyl rubber, sulfonated EPDM and other sulfonated elastomeric polymers. The thermoplastic polar resins having a halogen-carbon bond include polyvinyl chloride.

Abstract: Polymers containing pendent substituted ethylsulfonyl, vinylsulfonyl or styrylsulfonyl groups are useful as gelatin hardeners or can be crosslinked by bis-nucleophiles or by exposure to ultraviolet light.
