Abstract: The present invention relates to a hydraulic fluid composition comprising: (a) a base fluid and (b) as an anti-mist additive, an alkylene-vinyl ester copolymer having a molecular weight of between about 5,000 and about 100,000 and soluble in said base fluid. In another aspect, the present invention relates to a process for imparting flame retardancy and reduced wear characteristics to a hydraulic system which comprises adding to the hydraulic system the above-identified hydraulic fluid composition.
Abstract: This invention relates to a method of fabricating a thermoset elastomer which comprises the steps of: (a) fabricating a polyol having a molecular weight of between about 400 and about 15,000 and having a level of end group unsaturation of not greater than 0.04 milliequivalents per gram of polyol, said polyol being fabricated in the presence of a double metal cyanide catalyst, (b) reacting said polyol with a polyisocynate to produce an isocyanate-terminated prepolymer, and (e) reacting said isocyanate-terminated prepolymer with a chain extender other than ethylene glycol in a mold in order to produce the elastomer. Also claimed is the elastomer produced by the above method utilizing a one-shot technique.
Abstract: The present invention relates to a process for imparting anti-bacterial and anti-fungal properties to a polyurethane foam. Dissolving the pyrithione salt in an alkanolamine which is miscible with a polyol, makes this dissolved pyrithione an ideal candidate for use as a antimicrobial additive in this application. Prior use of pyrithiones in polyurethanes entailed using the powder form of zinc pyrithione. This was a dusty process as well as being difficult to disperse the pyrithione uniformly throughout the polyurethane foam. This invention overcomes both of these difficulties.

Abstract: Method for producing novel deterred granular nitrocellulose propellant powder compositions having a stable burn rate gradient. The invention comprises coating nitrocellulose propellant granules with a minor amount by weight of a polycaprolactone polymer which is soluble in nitrocellulose under conditions which cause the polymer to be gradually dissolved into the granules to produce maximum burn deterrence at the surface of the granules which gradually decreases inwardly therefrom to produce a desired burn rate gradient in the granules.
Abstract: A high energy explosive or propellant composition having low vulnerability to unplanned stimuli and containing a polyurethane polyacetal elastomer binder. Also claimed is a process for producing this composition.
Abstract: An aryl N,N'-bis cinnamamide compound having a formula comprising: ##STR1## wherein x equals an integer from 0 to 3; y equals an integer from 0 to 2; z equals an integer from 0 to 2; each R is individually selected from the group consisting of a lower alkyl group having 1 to 4 carbon atoms, a lower alkoxy group having from 1 to 4 carbon atoms, a halo group, a nitro group, an aryl group having 6 to 18 carbon atoms, and a fused unsubstituted or substituted aromatic ring when x is 2 or 3; and each R' and R" is individually selected from the group consisting of a lower alkyl group having from 1 to 4 carbon atoms, a lower alkoxy group having from 1 to 4 carbon atoms, a halo group, a nitro group or an aryl group having from 6 to 18 carbon atoms. These compounds are useful as U.V. light absorbers in plastics and cosmetics (e.g. sunscreens).
Abstract: A process for producing an alkylene oxide or mixture of alkylene oxides by a reaction which comprises reacting a C7 to C22 olefin or mixture thereof with an oxygen-containing gas in the presence of at least one molten nitrate salt.
Abstract: The present invention relates generally to open-cell polyurethane foams and, more specifically, to such foams which are halogenated-hydrocarbon blown and are essentially urea-free, together with a composition and method for the fabrication thereof.
Abstract: A stable, low viscosity polymer/polyisocyanate dispersion wherein the polymer is produced by polymerizing an ethylenically unsaturated macromolecular monomer with another ethylenically unsaturated monomer, together with a polyurethane foam, elastomer, adhesive, sealant, or coating produced therefrom and a method for fabricating the foam.
Abstract: The use of glycoside polyols together with diol or triol-initiated polyols in the production of polyurethane elastomers provides elastomers which are thermally stable at temperatures of 140.degree. F. or higher. These polyurethane elastomers are useful as thermoconductivity barriers in window holders exposed to high-temperature conditions, as engine mounts on automobiles, as encapsulators for electronic distributors, and the like.
