Abstract: An SiO.sub.2 -containing copper oxide-chromium oxide catalyst is obtained through heat treatment of copper oxide and chromium oxide, or of a precursor compound convertible into copper oxide or chromium oxide in the presence of an SiO.sub.2 component; it is characterized by the fact that, after the heat treatment,(a) the intensity ratio between the X-ray diffraction lines (XRD reflexes) of the copper oxide with d=0.232 nm and of the CuCr.sub.2 O.sub.4 spinel with d=0.240 nm formed through heat treatment, determined as the ratio of the reflex amplitudes, is 0.7 to 4.0:1, and(b) the copper mass, which is dissolved by stirring 10 g of the catalyst in 100 ml of 10 weight percent acetic acid at 20.degree. C. for 2 minutes, amounts to a maximum of 200 mg.

Abstract: Adhesive compositions are made from methacrylate ester monomers, elastomeric polymers having a Tg below -25.degree. C. and which are soluble in the monomers, core-shell polymers which swell in the monomers but do not dissolve therein, and free radical producing catalysts. These adhesive compositions when used in bonded assemblies exhibit a combination of high adhesive bond impact strength and high bulk tensile elongation.

Abstract: Acid-resistant copper oxide-chromium oxide catalysts for hydrogenation of fatty acids or fatty acid mixtures and/or the esters thereof are obtained through heat treatment of copper oxide and chromium oxide or of precursor compounds that are convertible into copper oxide or chromium oxide and which contain aluminum zirconium, cerium and/or lanthanum oxide as an additional metal component. The acid resistance is defined by the fact that the amount of copper which is dissolved by stirring 10 g of the catalyst for 2 minutes in 100 ml of 10 weight percent acetic acid at 20.degree. C., is a maximum of 200 mg.

Abstract: Preactivated organophilic clays useful as rheological control and gelling agents for organic liquids are made by dry blending the organophilic clays with free-flowing dry powder blends of 1,2-propylene carbonate and finely divided amorphous silica.

Abstract: Molding compositions having improved flexibility are made from blends of segmented copolyester elastomers and copolymers of ethylene and ethyl acrylate.

Abstract: Water-borne coating compositions are made, using as a thickening agent, a polygalactomannan having both hydrophilic and hydrophobic substituents.

Abstract: Animal litters having deodorizing properties are made from particulate moisture absorbent material and aluminum salts.

Abstract: The flavor protecting properties of interior container coating compositions are improved by the inclusion of cyclodextrins in the composition.

Abstract: Bis(4-cyanatophenyl)-1,1-ethane, a low viscosity liquid, is useful in wet filament winding, resin transfer molding and pultrusion processes.

Abstract: Citric ester compositions wherein the ester components contain about 1.5 to about 3 hydroxyl groups per molecule are useful as pigment grinding vehicles and as reactive diluents for thermosetting coatings.

Abstract: Cyanate esters of 4,4'-[1,3-phenylenebis(1-methylethylidene)] 2,2',6,6'-R-bisphenol when properly catalyzed, can be cured at temperatures in the range of about 250.degree. to about 300.degree. F. to obtain percent cyclotrimerization of the cyanate ester groups of at least 80 percent.

Abstract: Super-absorbent polymers having superior dryness properties when incorporated into absorbent articles are made from acrylic acid and crosslinking agent polymerized under controlled conditions.

Abstract: Alkyl and hydroxyalkyl ethers of polygalactomannans are further modified with long chain haloalkanoic acids. The resulting derivatized polygalactomannans are useful as thickening agents in aqueous systems, particularly in combination with surfactants at acidic pH.

Abstract: Adhesive compositions are made from methacrylate ester monomers, elastomeric polymers having a Tg below -25.degree. C. and which are soluble in the monomers, core-shell polymers which swell in the monomers but do not dissolve therein, and free radical producing catalysts. These adhesive compositions when used in bonded assemblies exhibit a combination of high adhesive bond impact strength and high bulk tensile elongation.

Abstract: Toothed-wheel shaped particles are used as catalysts in the dehydrogenation of hydrocarbons, particularly ethylbenzene to styrene.

Abstract: Glass containing polyacetal articles are first etched in an acid bath and then treated with an organosilane or titanate to improve adhesion to the articles. Such treated articles can be more easily coated with adhesives than non-treated articles.
