发明人：TAZZIA CHARLES L
权利人:BASF CORP
摘要:The invention provides a process for preparing an allophanate-containing compound in the presence of a metal catalyst and a tertiary amine. In a preferred process, the tertiary amine compound also has a hydroxyl group. The hydroxyl group can react with the isocyanate functionality. Also disclosed is a process in which an allophanate-containing compound is prepared with copper acetate monohydrate as a catalyst. The allophanate-containing compound is used as a curing agent in coating compositions, particularly electrocoat coating compositions. The coating compositions are used to coat articles.

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 :Synthesis of vinyl polymers by controlled radical polymerization
发明人：WHITE DANIELA; O'DWYER JAMES B
权利人:PPG IND OHIO INC
摘要:A controlled free radical polymerization process, which includes the steps of: adding a monofunctional iniferter compound to an oxygen-free solvent; heating the solution to a temperature sufficient to allow the iniferter compound to form two carbon centered radical residues; adding a first monomer composition comprising one or more monomers to the solution containing the radical containing residues; polymerizing the first monomer composition to form a quasi-living polymer; and optionally polymerizing a second monomer composition comprising one or more monomers, which are different than the first monomer composition. The resulting non-random copolymer having the general formula:n nφ-[-A p -B s -] t -φn nwhere A and B are different compositions of ethylenically unsaturated monomers; p is an integer from 1 to 1,000; s is an integer from 0 to 1,000; t is an integer from 1 to 100; and φ is a residue from the iniferter.

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 :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.
