Abstract: The present invention relates to a process for distillatively removing pure trioxane from a feedstream (I) comprising trioxane in a proportion of at least 50% by weight, based on the total weight of the feedstream (I), and additionally formaldehyde and water, which comprises feeding the feedstream I and a further aqueous stream (II) which does not contain any components extraneous to the feedstream to a dividing wall column (TWK1) having a dividing wall TW which is arranged substantially perpendicularly and divides the column interior into a feed region (A1), a withdrawal reaction (B1), an upper combined column region (C1) and a lower combined column region (D1), and drawing off from the first dividing wall column (TWK1) a bottom stream (III) comprising pure trioxane and a sidestream (IV) at the withdrawal region (B1), comprising pure water.

Abstract: The present invention relates to a coating material formulation comprising a mixture comprising as component a1 at least one surfactant and as component a2 at least one compound corresponding to the general formula (I) R1—O—(CH2—CHR2—O)n—(CH2—CH2—O)mR3??(I) in which R1 is optionally substituted phenyl, C4-C14 alkyl, R2 is C1-C8 alkyl, R3 is hydrogen, C1-C6 alkyl, benzoyl, acetyl, acryloyl, methacryloyl, n has an average value of 0 to 10, m has an average value of 1 to 10, where n+m?10 and m>n, and the alkylene oxide structural units, which are different if appropriate, can be distributed randomly or arranged in blocks, 1%-95% by weight of film-forming binders and resins, 0%-80% by weight of fillers, 0%-40% by weight of pigments, 0%-20% by weight of additives and 0%-90% by weight of organic solvents and/or water, the sum of the weight percentages being 100% by weight, and to the use of the mixture of the invention for lowering the surface tension in a coating material by addition to the coating mater

Abstract: A multi-stage emulsion polymer containing at least one first domain having a glass transition temperature Tg of from −10 to +40° C. and at least one second domain having a Tg of from +50 to 120° C., the weight ratio of the first domain to the second domain being within the range from 90:10 to 50:50. The first and/or the second domain containing from 0.1 to 10% by weight of a nitrogen-coutaining adhesion monomer and the first domain containing at least 10% by weight of vinyl aromatic compounds and/or the second domain containing at least 15% by weight of vinyl aromatic compounds and/or C4 to C12 alkylmethacrylates.

Abstract: It is shown that TPL-2 is responsible for phosphorylation of p105 and its resultant proteolysis, which leads to p50 Rel translocation to the nucleus. Accordingly, the invention provides TPL-2 as a specific regulator of the activation of NF&kgr;B, and thus as a modulator of inflammatory responses in which p105 is involved, and as a target for the development of compounds capable of influencing NF&kgr;B activation.

Abstract: In a process for finishing neopentyl glycol by cooling, crystallizing and comminuting a neopentyl glycol melt and subsequent packing of the resulting neopentyl glycol particles in storage or transport containers, the melt is cooled at the commencement of cooling for at least 1/10 minutes without use of a coolant or with use of a coolant having a temperature in the range from 50 to 120° C. and the product is packed at a temperature below 30° C.

Abstract: A process for preparing radiation-curable, urethane-functional prepolymers by reacting an isocyanate-functional component A with an OH-containing component B, wherein either component A embraces two different isocyanate compounds A1 or one isocyanate compound A1 and at least one isocyanate compound A2 or component B embraces at least two different compounds B1. Also, the prepolymers obtainable by the process and the radiation-curable formulations comprising them. Furthermore, the use of the radiation-curable formulations for coating substrates, a method of coating substrates, and the coated substrates themselves.

Abstract: Novel substituted 3-fluoroalkoxybenzoyl halides of the formula ##STR1## where Hal is fluorine or chlorine,R.sup.1 is chlorodifluoromethyl, difluoromethyl, 1,1,2,2-tetrafluoroethyl, 2-bromo-1,1,2-trifluoroethyl, pentafluoroethyl or 1,1,2,3,3,3-hexafluoropropyl andR.sup.2 is hydrogen, orR.sup.1 is chlorodifluoromethyl or trifluoromethyl and R.sup.2 is chlorine, and processes for their preparation.The novel 3-fluoroalkoxybenzoyl halides are valuable intermediates for the synthesis of biologically active compounds, for example of 2-(3-fluoroalkoxyphenyl)-3,1-benzoxazin-4-ones, which are herbicidally active.
