Abstract: The present invention provides a composition and a method for reducing the production of persistent bio-accumulative and toxic pollutants in solid carbonaceous reduction reactions in carbochlorination processes.

Abstract: A dust-proof element for reducing creeping dispersion of dust along a free surface formed as one of locally limited dust trap element (5) and dust barrier (7) having a surface with an artificial pimpled microcrystalline structure with bumps and indentations having a size in a range from 5 to 100 &mgr;m and spaced from each other by a distance from 5 to 200 &mgr;m, and a method of protecting hand-held tools and working tools with the dust-proof element.

Abstract: Compositions and methods for use in temporarily protecting a paint booth surface are described which allow removal of the protective composition and undesired overspray with a low pressure stream of water. The protective composition is a mixture containing at least a hydrophobic solvent comprising a C1-4 alkyl ester of a C16-18 fatty acid, a surfactant and a thickener.

Abstract: The adhesion between a metal surface, e.g., a copper circuit trace, and a polymeric material, e.g.

Abstract: The invention concerns a coagulating agent for liquid crystal solutions with a base of cellulose substances, characterized in that it contains at least one water soluble additive selected from the group consisting of ammonia, amines of salt of these compounds, the additive being such that the pH of the said coagulating agent is greater than 6. A preferable additive is a salt selected from the group consisting of ammonium formates, acetates and phosphates, mixed salts of these compounds, or mixtures of these constituents, in particular diammonium orthophosphates (NH4) 2 HPO4. The invention also concerns a method for spinning a liquid crystal solution with a base of cellulose substances, using a coagulating agent as per the invention, in particular the method called “dry-jet-wet-spinning” as well as spun articles, fibers or films, obtained by these methods.

Abstract: Provided is a process for preparing an at least bis-carbamate functional 1,3,5-triazine by contacting an at least diamino-1,3,5-triazine, an acyclic organic carbonate and a base, as well as certain novel compositions producible thereby. Also provided are substantially halogen contamination free crosslinker compositions comprising the products obtainable by the process, and curable compositions based upon these crosslinkers.
