标 题:Process for the synthesis of o-substituted oxime compounds
发明人：CHEMPOLIL THOMAS MATHEW
权利人:ALLIED SIGNAL INC
摘要:A novel process for the production of O-substituted oximes is disclosed. The process involves reacting an oxime with an alkali-metal hydroxide optionally in a solvent which forms an azeotrope with water to form a mixture of the alkali metal salt of the oxime and water, removing all or a portion of the water by distilling the mixture azeotropically and reacting the distilled mixture with an alpha halo carboxylic acid.

标 题 :Removal of acrylonitrile from latex with oximes
发明人：SENYEK MICHAEL L; COSTANZA ALBERT J
权利人:GOODYEAR TIRE & RUBBER
摘要:Acrylonitrile is a monomer that is widely used in the synthesis of a vast variety of polymers. Undesirable quantities of unpolymerized residual acrylonitrile are often present in these acrylonitrile polymers. This residual or free acrylonitrile dissolved in an acrylonitrile polymer and/or its emulsifier system and the water phase used in its polymerization can be reduced significantly in concentration by treatment with oximes. Oximes react with acrylonitrile by an oxygen-cyanoethylation reaction which results in the formation of a cyanoethyl oximino ether linkage.

标 题 :Discoloration prevention of phenolic antioxidants
发明人：COLLONGE JACQUES H; WIDMER HANS
权利人:GOODYEAR TIRE & RUBBER
摘要:Detrimental color change of phenolic antioxidants during production, storage and use in rubbers is inhibited by adding during the synthesis of the phenolic antioxidant a disubstituted hydroxylamine to the catalyst neutralization solution and a substituted oxime together with a disubstituted hydroxylamine to the reaction mixture prior to filtration.

标题 :Method of preparing a polymeric coating composition
摘要:A method of preparing a storage-stable one-part reactive liquid thermal curing polymeric coating composition from an isocyanate-functional polymeric compound which has a substantial portion of its isocyanate groups masked with an isocvanate masking agent, and a crosslinking agent which is substantially insoluble in aprotic solvents. These liquid compositions are homogeneous even when free of solvents. Preferably the crosslinking agent is a crystalline polyol. The method involves the synthesis of a solubilizing oligomer which is formed by the partial reaction of the crosslinking agent and the unmasked isocyanate-functional polymeric compound. The thermal curing of these compositions results in polymeric coatings which possess superior physical properties. These cured coatings are particularly useful in the manufacture of retroreflective sheeting.
