Abstract: The (6-hydroxy-chroman-2-yl) acetic or carboxylic acid derivatives useful as antioxidants and a method for preparing these derivatives from hydroquinones and intermediates in this synthesis as well as the use of these derivatives as intermediates in the preparation of optically active alpha-tocopherol.

Abstract: A composition effective as a lubricant for incorporation in, and to enhance the heat stabilization of, an ABS resin, and consisting essentially of ethylenediamine bis-stearamide and a substantially minor amount of at least one of malic acid, citric acid, and gallic acid; and the method of preparing said composition by heating ethylenediamine bis-stearamide to a melting temperature and dissolving in its melts the substantially minor amount of at least one of those three acids.

Abstract: A minor amount of a radical trap, that is, an organic compound readily reacting with an organic radical, when combined with a polyolefin having a melt index of from about 0.2 to about 10, can be associated with 70 per cent tertiary butyl hydroperoxide (containing about 30 per cent water). In the event of accidental conflagration of the combination, the combustion continues at a moderate rate, thereby avoiding the propensity toward troublesomely rapid burning of unmodified aqueous 70 per cent TBHP. Container liners should have a polyolefin thickness of 0.7 to 7 mm, the polyolefin containing such radical trap in a concentration of from about 0.1 to about 5 per cent, generally 0.2 to 2 per cent. If particulate polyolefin is used, the radical trap concentration should be from about 10 to about 100,000 parts per million parts of aqueous TBHP. A concentration of polyolefin particles from about 0.6 per cent to about 6 per cent by weight of the TBHP is suitable.

Abstract: Compounds of the formula: ##EQU1## WHEREIN X is oxygen or sulfur,a is an integer from 2 to 6,b is an integer from 3 to 40, andR is ##SPC1##WhereinR.sub.1 is an alkyl group of 1 to 8 carbon atoms,R.sub.2 is hydrogen or an alkyl group of 1 to 8 carbon atoms, andX is an integer from 0 to 6Are useful as antioxidants for organic materials normally subject to oxidative deterioration, such as polyacetals, polypropylene, and nylon, in amounts of from about 0.005 to about 5% by weight of the composition.

Abstract: Metal/metal oxide coated articles having selective reflectance and transmittance of radiation over an extended spectral range are provided by a combination of alternately disposed coating layers of metal and metal oxide, the metals of the metal layer being silver, chromium, iron, cobalt or nickel and the metal oxide being copper oxide. Chemical or electroless plating techniques are disclosed for the production of such articles. Uniform oxide coatings are formed by first depositing metal films, then treating them with surfactants to promote uniform oxidation and then exposing them to an oxidizing environment.
