Stabilizer compositions comprise phosphate of the formula I or II, a phosphite of the formula III, and a phenol of the formula IV as these formulas are defined herein. The stabilizer compositions are useful for stabilizing polymers. Methods for making stabilized polymer compositions involve intermixing the stabilizer compositions and the polymers, e.g., by extruding, pelletizing, and/or molding.

This invention relates to an UV stabilizing additive composition comprising an ortho-hydroxy triazine compound, a hindered hydroxybenzoate compound and optionally a hindered amine compound. This additive composition may be used to stabilize materials from UV radiation. This invention also contemplates a method of stabilizing a material by contacting the material with the UV stabilizing additive composition.

UV stabilizing additive composition

The present invention relates to a process for improving the shelf life of a hindered phenol antioxidant comprising the step of intimately mixing the hindered phenol antioxidant with a sulfur-containing peroxide decomposer. The inventors have discovered that mixing the peroxide decomposer with the hindered phenol antioxidant reduces the tendency of hindered phenols to yellow with age. This increases the desirability of the hindered phenol because it will not impart color to polymer systems. The present invention also relates to a composition produced from the process described above, and stabilized compositions and additive packages containing the composition produced from the above-described process.

Process for improving the shelf life of a hindered phenol antioxidant

A process for leaching gold, silver, platinum and palladium wherein an aqueous leaching solution containing bromine and bromide ion contacts a precious metal source to produce an aqueous leachate. A precursor composition for producing an aqueous leaching solution for leaching gold, silver, platinum and palladium. A process for electrogenerating bromine and a process for leaching gold, silver, platinum and palladium wherein bromine is electrogenerated and contacts a precious metal source to produce an aqueous leachate. A process for leaching gold, silver, platinum and palladium wherein bromine is electrogenerated from a solution containing chloride ions and bromide ions.

Inorganic perbromide compositions and methods of use thereof

A method for reducing plant water loss by closing stomatal openings and reducing the transpiration rate. In particular, a water loss reducing composition made of an osmo-adjusting solute such as sorbitol or xylitol is applied to plants. The solution is applied to the root zone by drenching regularly or prior to water deficiency, and preferably includes between about 0.5 and about 25 weight percent of the water loss reducing and conditioning agent.

Method of using sorbitol or xylitol for plant water loss reducing agent

Osmo-adjusting solutes, particularly polyols and/or monosaccharides, are used to control the growth of plants. In particular, aqueous solutions of sorbitol or xylitol are used to reduce plant height and increase stem diameter. The solutions preferably include between about 0.05 and about 25 weight percent of the osmo-adjusting solute, and are applied to the root zone by drenching regularly or prior to transplanting. The solutions are also shown to be effective for conditioning plants for hardiness against certain environmental and handling stresses.
