Abstract:
An anhydrous battery or cell comprises an anode, a cathode, an electrolyte and an anhydrous solvent, the cathode comprising a mixture of p-doped polyacetylene in admixture with 5-75% by weight of an electrically conductive material e.g. graphite or carbon black.Electrolytes include hexafluorophosphate, perchlorate etc. and suitable solvents are propylene carbonate, sulfolane etc.
Abstract:
An anhydrous battery is provided having a high drain capacity and improved efficiency comprising a metal or alloy anode, a cathode comprising a p-doped polyacetylene, an electrolyte and an inert anhydrous solvent forthe electrolyte.
Abstract:
A triggered response composition comprising: one or more polyelectrolytes in contact with an aqueous system that is stable and insoluble in an aqueous system at relatively high ionic strength equivalent to 0.5M sodium chloride or higher or base concentration of between 1.0 M to 2.5 M or higher and that disperses, disintegrates, dissolves, destabilizes, swells, or combinations thereof, wherein the chemical/physical response of the composition is triggered upon one or more ionic strength or base strength changes to the aqueous system; wherein the polyelectrolyte is one or more alkali soluble polymers comprising: (a) 5-70 weight percent of acidic monomers selected from methacrylic acid, 2-methylpropionic acid or acrylic acid; (b) 30-95 weight percent of one or more non-ionic vinyl monomers selected from butyl acrylate, styrene and methyl methacrylate and optionally, (c) 0.01 to 5 weight percent of one or more metal cross-linking agents.
Abstract:
Emulsion polymers are disclosed which contain selectively swellable emulsion polymer functionalities and which are cross-linked before film formation to an extent that still allows the polymers to form a film upon application, which film is removable with a stripper solution containing swellant for the polymer functionality. When the polymers are formulated into sacrificial coatings, the polishes produce detergent resistant and removable finishes.
Abstract:
An anhydrous cell comprises an anode, a cathode, electrolyte and anhydrous solvent, the cathode comprising a mixture of polyacetylene powder and an electrically conductive material and the anode being an inorganic intercalating anode. Suitable materials for the anode include tungsten dioxide, titanium disulfide, vanadium diselenide and vanadium disulfide.
Abstract:
Aqueous coating compositions containing (1) a first polymer containing reactive functional groups with a selected level of carboxylic acid functionality and (2) a polyfunctional crosslinker agent containing functional groups that are reactive with appropriate functional groups of the first polymer, are disclosed. The two-component polymer compositions provide a combination of durability and ready removability of the final coating after curing. Two-component polymer compositions based on the first polymer containing hydroxyl functionality in addition to carboxylic acid functionality and use of a polyisocyanate as the polyfunctional crosslinker agent are especially useful as floor polish compositions.
