Abstract: Pneumatic tire sidewall compositions are disclosed comprising blends of a halobutyl rubber, a high unsaturation rubber and an oil extended terpolymer of ethylene, propylene, and a diene wherein the oil extended terpolymer contains from between 25 to 150 phr of a paraffinic or naphthenic oil. These triblends provide sidewalls of unexpectedly improved flex resistance, even as compared to similar triblend compositions in which similar amounts of oil are included, but in which an oil extended terpolymer is not employed. Furthermore, methods of preparing such compositions are also disclosed comprising preparing an oil extended terpolymer, and then blending that terpolymer with the halobutyl and high unsaturation rubbers.

Abstract: Reinforced molding compounds are disclosed comprising elastomer modified thermosetting unsaturated polyesters which include conjugated diene butyl rubber elastomer copolymer dispersed therein, and which further include inorganic particulate filler material and a free radical polymerizable monomer. Preferably, they also include a thermoplastic component, and such compounds have improved surface appearance, toughness and impact strength as demonstrated by the molded articles produced from such a low profile system.

Abstract: Methods for preparing reinforced molding compounds are disclosed, comprising preparing a first paste component from a mixture of a thermosetting unsaturated polyester component, a free radical polymerizable monomer component and an inorganic particulate filler component, preparing a second paste component from a conjugated diene butyl elastomer copolymer component, a free radical polymerizable monomer component, and an inorganic particulate filler component, and combining the first and second paste components in order to produce an elastomer modified thermosetting unsaturated polyester molding compound having improved surface appearance, toughness and impact strength. Preferably, one or both of the paste components will include a thermoplastic polymer additive component to provide low profile qualities to the product.

Abstract: Methods for producing rubbery polymers are disclosed comprising forming a slurry of such rubbery polymers, preferably butyl rubber prepared from a mixture of a C.sub.4 to C.sub.8 isoolefin and a C.sub.4 to C.sub.10 conjugated mutiolefin in a low temperature reaction zone in the presence of a Friedel-Crafts catalyst and an organic halide diluent, passing that slurry into an overflow passage for transporting the slurry to a recovery system, and injecting a mixture of a hydrocarbon liquid having a boiling point above the boiling point of the organic halide and a polar organic catalyst quenching agent into said overflow passage at a point adjacent to the outlet from the reaction zone in order to prevent continued production of polymer in the overflow passage and to maintain the overflow passage substantially free of agglomerates.

Abstract: Sulfur-containing petroleum oil feedstocks which include heavy hydrocarbon constituents undergo simultaneous desulfurization and hydroconversion by contacting and reacting such feedstocks with sodamide in the presence of hydrogen and at elevated temperatures. The mixture of reaction products resulting from the above procedure is separated to give a sodium sulfur salt by-product, and a petroleum oil product which has been substantially desulfurized and demetallized, as well as being significantly improved as indicated by a reduced Conradson carbon content and an increased API gravity relative to the feedstock. Sodamide is regenerated from the sodium sulfur salt by-product and can be recycled for reaction with additional feedstock.
