Abstract: Disclosed is a process for preparing shaped alumina particles for catalysts or catalyst supports by passing droplets of an aqueous slurry of a rehydratable alumina composition through a shaping medium, such as a column of water-immiscible liquid. The alumina composition undergoes rehydration while being shaped as it passes through the shaping medium, and accordingly, firm, discrete alumina bodies are produced.

Abstract: The disclosure relates to a new class of compounds useful in stabilizing organic materials against the effects of heat and light, such materials especially including polymers such as polyolefins. The new compounds are hydrazine complexes of nickel thio-bis-phenolates, where the thio-bis-phenol is of the formula, ##STR1## where R is selected from the group consisting of hydrogen, normal alkyl or normal alkenyl, and R.sub.1 is selected from the group consisting of a normal, secondary, tertiary or cyclic alkyl group. The hydrazines used in making the complexes are of the formula ##STR2## where R.sub.2, R.sub.3 and R.sub.4 are independently chosen from the group hydrogen and primary, secondary and tertiary alkyl groups consisting of 1 to 8 carbon atoms and R.sub.3 and R.sub.4 may be joined together to form a heterocyclic structure.

Abstract: Sulfonyl carbazates containing at least one group of:--SO.sub.2 --NHNH--COO--wherein the oxygen and the sulphur atoms attach to various organic groups are useful as high temperature blowing agents for gas-expandable polymers. Additionally, novel polyfunctional and secondary-alkyl substituted sulfonyl carbazates have been discovered.

Abstract: This invention relates to the use of bisulfite-terminated oligomers as dispersants for solid particulate matter, i.e., low molecular weight bisulfate-terminated polymers containing carboxylate groups and either cyano or carbomethoxy moieties are improved dispersants for solid particulate matter like pigments such as titanium dioxide, clay, calcium carbonate, talc, and zinc oxide, as well as for organic pigments. Particularly, these dispersants have been found useful for stabilizing paper coating compositions.

Abstract: Component adhesion in systems comprising (1) rubber, (2) an adhesive composition and (3) a fibrous reinforcement is greatly improved through use of an adhesive composition comprising a 1-aza-3,7-dioxabicyclo[3.3.0]octane in combination with a reinforcement of aramid fibers. The rubber systems are useful in the formation of tires, belts, hoses etc.

Abstract: A process for preparing hydrazodicarbonamide directly from a ketazine and urea in water without any acid catalyst according to the following reaction is disclosed. ##EQU1## wherein the R groups may be the same or different.

Abstract: A process for preparing N',N'-disubstituted acid hydrazides by reacting N'-monosubstituted acid hydrazides with aldehydes in the presence of hydrogen and a hydrogenation catalyst is disclosed.

Abstract: Scale formation in industrial waters, such as cooling water, is inhibited by adding a bisulfite terminated oligomer such as sodium bisulfite-terminated acrylic acid-acrylonitrile oligomer.

Abstract: Flame retardant blends of ABS or polyurethanes with 2,2', 3,3',4,4', 5,5',7,7,7',7'-dodecachloro-1,1', 2,2',5,5',6,6'-octahydro-2,2',5,5'-methanobiphenyl, with or without antimony compounds, are disclosed.

Abstract: Derivatives of diphenylamine or phenylnaphthylamine of the types ##SPC1##Where R.sub.1, R.sub.9 and R.sub.12 are phenyl or p-tolyl groups and the remaining R's, X and Y may be alkyl or various other substituents, are useful antioxidants for lubricating oils or for various polymeric substrates (e.g. polypropylene) especially in combination with a dialkyl thiodipropionate.
