Abstract: This invention relates to a pressure sensitive adhesive compositions which include an emulsion of a metal neutralized sulfonated copolymer of isoprene/sodium styrene sulfonate, wherein the neutralized sulfonated copolymer has about 5 to about 250 meq. of neutralized sulfonate groups per 100 grams of the neutralized sulfonated copolymer, and less than about 50 parts by weight of an emulsion of a preferential polar plasticizer, and less than about 300 parts by weight of an emulsion of a hydrocarbon tackifying resin of a petroleum or coal tar distillate, having about 4 to 12 carbon atoms, wherein the hydrocarbon resin is composed of aliphatic dienes and monoolefins per 100 parts by weight of the neutralized sulfonated copolymer.

Abstract: This invention relates to a method for upgrading heavy oils for use in subsequent hydrocarbon processing. The process is especially suitable for removing metals which are in the form of nickel or vanadium organic compounds and for lowering the Conradson Carbon Residue of the resulting oil. The process includes the steps of diluting the heavy oil with a solvent which completely solvates the oil and subjecting the resulting mixture to an ultrafiltration step using selected membranes.

Abstract: An improved electrochemical cell comprises an alkali metal anode, a cathode, an oxidant of at least one quaternary ammonium polyhalide salt, and a dipolar aprotic electrolyte containing an ionizable salt of an alkali metal. A specific example includes a lithium anode, a carbon cathode, a tetraalkylammonium tribromide salt and an electrolyte of one mole lithium hexafluoride dissolved in propylene carbonate, which cell provides an open circuit voltage of about 3.6 volts. The oxidant can be incorporated in the cathode structure or be added independently to the cell, e.g., by use of a circulating electrolyte.
