摘要:The present invention provides a composition, and for the use of this composition as a catalytically active composition in processes for synthesis of chemical compounds, especially for hydroformylation of olefinically unsaturated hydrocarbon mixtures. Preferably, the composition comprises a metal complex, especially an Rh complex having a phosphine or phosphite ligand, on an inert porous carrier, and is loaded for the purposes of the hydroformylation with the aldol by-product of the desired aldehyde, in the manner of an application of the 'Supported Liquid Phase' (SLP) concept.

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:Synthesis of modified epoxy resins for cathodic electrodeposition with catalyst deactivation and diol modification
发明人：REUTER HARDY; JOUCK WALTER; OTT GUENTHER
权利人:BASF LACKE & FARBEN
摘要:Epoxy resins for preparing water-dispersible binders for cathodic electrodeposition coating materials, the epoxy resin being preparable by reacting a) polyepoxides having at least one glycidyl group per molecule b) and, optionally, up to 60% by weight, based on the overall epoxy resin reaction product, of aliphatic and/or alicyclic hydroxy compounds having preferably two or on average less than two hydroxyl groups per molecule and a molecular weight of less than 9000 g/mol, c) in the presence of a catalyst consisting of neutral metal salts, such as alkali metal salts and alkaline earth metal salts, zinc salts and nickel salts of tetrafluoroboric, tetrachloroboric, hexafluoro- antimonic,hexachloroantimonic,hexafluorophosphoric, perchlorate and periodic acid, and d) adding a deactivating agent which prevents the epoxy groups reacting further or effectively reduces the rate of such reaction as soon as the phenolic hydroxyl groups have already substantially reacted and at least 0.6% by weight of epoxy groups are still present, based on the overall weight of the epoxy resin reaction product.\\!
