Abstract: Processes for the production of acetic acid by carbonylation of methanol, and reactive derivatives thereof, in a reaction mixture using a rhodium-based catalyst system with at least one catalyst stabilizer selected from the group of ruthenium catalyst stabilizers, tin catalyst stabilizers, and mixtures thereof are provided. The catalyst stabilizers minimize precipitation of the rhodium metal during recovery of the acetic acid product, particularly in flasher units in an acetic acid recovery scheme. Stability of the rhodium metal is achieved even when the acetic acid is produced in low water content reaction mixtures in the presence of an iodide salt co-promoter at a concentration that generated an iodide ion concentration of greater than about 3 weight % of the reaction mixture. The stabilizing ruthenium or tin compounds may be present in the reaction mixture for the production of acetic acid at molar concentrations of ruthenium or tin metal to rhodium of about 0.1:1 to about 20:1.
Abstract: The invention relates to UV curable, low gloss overprint varnish coating formulations and cured coatings prepared therefrom. The low gloss overprint varnish formulations contain a Michael addition resin, a polyamide powder and a reactive monomer.

Abstract: UV curable, liquid, oligomeric compositions are prepared from the reaction product of a Michael addition oligomer and an isocyanate capped polybutadiene. The UV curable, liquid, oligomeric compositions can be cured in the presence of fragrances to form articles that are characterized by a controlled release of the fragrance over time.

Abstract: The present invention provides a process for the preparation of low styrene content resins prepared by first reacting an unsaturated carboxylic acid, its corresponding anhydride or mixtures thereof with a monohydric alcohol, DCPD and water and reacting the product of the first step with a polyol and optionally an oil containing unsaturation, its corresponding fatty acid or mixtures thereof.
Abstract: The uncrosslinked liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate-functional donor compounds with multifunctional acrylate acceptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from ≧1:1 to ≧13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate in the presence of a catalyst comprising an epoxy moiety and a quaternary salt. Unusable gelled or cured oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.
Abstract: The invention relates to a method useful in removing etch residue from etcher equipment parts. The compositions used are aqueous, acidic compositions containing flouride and polar, organic solvents. The compositions are free of glycols and hydroxyl amine and have a low surface tension and viscosity.
Abstract: The invention relates to low molecular weight LPA surface quality enhancers derived from C36-44 dimer acids capped with a glycol or a polyether polyol. The capped dimer acids are incompatible in the cured matrix of a polyester molding composition.

Abstract: A process for the preparation of dicyclopentadiene (DCPD) modified unsaturated polyester resins is described where the polyester resins have reduced levels of gel particles.
Abstract: The present invention relates to laminates prepared using reactive hot melt adhesives. The reactive hot melt adhesives are the reaction product of a polyurethane prepolymer and a vinyl chloride based thermoplastic copolymer.
Abstract: The present invention relates to aldehyde resins having low amounts of free aldehydes and methods of preparing the resins. The reduction in the amount of free aldehydes is accomplished by adding an amino acid to the resin formulation prior to form the resin.
Abstract: The present invention relates to composite roof structures and their preparation. The composite roof structure is prepared by applying a one-part, moisture curable, foaming, polyurethane adhesive composition to the roof deck, placing the roofing material in contact with the adhesive composition, and allowing the adhesive mixture to foam, fill, and cure. If multiple layer of the roofing material are used to form the composite roof structure, then the above procedure may be used to adhere each of the roofing material layers.

Abstract: The invention relates to an aqueous phosphoric acid etch bath composition with a readily soluble silicon containing composition. The baths are used in the etching step of composite semiconductor device manufacturing.
Abstract: A top reading bituminous paving depth gauge is used to determine the thickness of paving layers. The gauge comprises a depressible rod operatively associated when a rod support system comprising an upper portion having a graduated measuring gauge fixed on the rod support system and a bottom support devise fixed to the lower end of the rod support system. The bottom or the support device acts as a foot for the measuring gauge and also acts to receive the lower portion of the depressible rod. The top reading bituminous paving depth gauge operates without any washers on the measuring depressible rod to prevent false measurements due to the presence of large aggregates.
Abstract: The present invention relates to solvent free, moisture-curable, reactive hot melt adhesive compositions that are solid at room temperature, methods of making the compositions, and laminates prepared using the compostions. The compositions are a mixture comprising an isocyanate terminated prepolymer and a thermoplastic vinyl chloride copolymer.
Abstract: The invention relates to a process for preparing polyester resins by first reacting a carboxylic acid or its corresponding anhydride with a saturated monohydric alcohol to form the half ester and then reacting the half ester with a polyol. In addition to the polyol, up to 45 wt % of all oil containing unsaturation can be present in the second step.
Abstract: An electric circuit for a system to prevent accidental discharge of hot-mix asphalt at asphalt plants with multiple silos includes a manual switch which energizes a relay holding the circuit closed. A time delay relay is also energized to provide a time period to determine whether the process should continue. When the time delay times out, a solenoid is energized to open a hot mix storage silo. A closed circuit TV camera and a system of flashing lights are included to provide a fixed view of the loading area with a monitor at the control panel. When hot-mix asphalt is to be discharged into a truck, a switch is activated which causes a light beneath the bin to flash. This identifies the bin selected to open. The TV monitor is viewed and the position of the truck can now be visually confirmed along with the flashing light on the bin that has been activated. The manual switch must be pushed in order to complete the discharge of the hot-mix asphalt from the bin.
