Abstract: A composition can be used for producing a PMMA-based cast polymer with a low styrene content using urea (derivatives) as a formulation constituent, and a hydrophilic inorganic compound as a filler. It is possible to produce PMMA-based cast polymers and mouldings having surprisingly high mechanical stability from the composition.

Abstract: Compositions have a high content of saturated or unsaturated isoparaffinic hydrocarbons with 12-24 carbon atoms and a polyalkyl (meth)acrylate. A method prepares said compositions to promote the raise of the flash point of hydraulic fluids where a good low temperature flow is important, e.g. compressor oils, shock absorber fluids, power steering fluids, and central hydraulic fluids.

Abstract: The invention relates to a method for producing an alkali metal alcoholate solution L1 in an electrolysis cell E which comprises at least one cathode chamber KK, at least one anode chamber KA, and at least one central chamber KM lying therebetween. The interior IKK of the cathode chamber KK is separated from the interior IKM of the central chamber KM by a separating wall W comprising at least one alkali-cation-conductive solid ceramic electrolyte (=“AFK”) F (e.g. NaSICON). F has the surface OF. A part OA/MK of the surface OF directly contacts the interior IKM, and a part OKK of the surface OF directly contacts the interior IKK. The surface OA/MK and/or the surface OKK comprises at least one part of a surface OFΔ. OFΔ is produced from a pre-treatment step in which F is produced from an AFK F′ comprising the surface OF′. For this purpose, AFK is removed from F′ by carrying out a compressed air blasting process on the surface OF′ using a solid blasting agent N, and the AFK F with the surface OF comprising the surface OFΔ formed by the compressed air blasting process is obtained. During the electrolysis process for producing the alkali metal alcoholates with F instead of F′, an improved conductivity is provided, whereby for a constant current density, a lower voltage can be used.
