摘要： The present invention relates to a polyurea coating composition comprising (A) a polyisocyanate; (B) a polyaspartic ester; and (C) an aspartic ester. The polyaspartic ester (B) is represented by the structure below:

where Z=a cycloalkyl, alkyl or aryl group, R1, R2=alkyl groups containing 1-10 carbon atoms; and n=2-4. The aspartic ester (C) is derived from a secondary heterocyclic amine in a 3-7 membered ring compound bearing at least one secondary amine functionality. This invention also relates to use of a polyurea coating composition comprising (A)-(C) for the preparation of a polyurea coating. This invention further relates to a process for preparing a polyaspartic/aspartic ester mixture in-situ by initially reacting an ester of fumaric acid or maleic acid with a polyamine and then reacting the unreacted ester of fumaric acid or maleic acid to completion with a secondary heterocyclic amine. This method makes it possible to prepare a polyurea coating without maleic acid or fumaric acid esters thereby providing a safer and more environmentally friendly product.

摘要： A process for producing a coated transition metal oxide involves subjecting a transition metal oxide and a pyrogenically produced lithium titanate and/or pyrogenically produced lithium aluminate to dry mixing. A coated transition metal oxide is obtainable by this process; and cathode for a lithium ion battery and a lithium ion battery containing such coated particles is useful.

摘要： The present invention relates, in a first aspect, to a dividing wall W suitable for use in an electrolysis cell E. The dividing wall W comprises a frame element R that forms an edge element RR and a separating element RT. The frame element R comprises two opposite parts R1 and R2, with at least two alkali metal cation-conducting solid-state electrolyte ceramics FA and FB disposed therebetween. The separating element RT lies between alkali metal cation-conducting solid-state electrolyte ceramics encompassed by the dividing wall W and separates these from one another. It is a feature of the invention that the two parts R1 and R2 are secured to one another by at least one securing element BR at the edge element RR and at least one securing element BT at the separating element RT.
Compared to the cases according to the prior art in which the dividing wall W encompasses the solid-state electrolyte in one piece, this arrangement is firstly more flexible since the individual ceramics have more degrees of freedom available in order to react to fluctuations in temperature, for example by shrinkage or expansion. This increases stability with respect to mechanical stresses in the ceramic. At the same time, the mechanical stability of the arrangement of the at least two solid-state electrolyte ceramics between the parts R1 and R2 is increased in that the parts R1 and R2 are secured to one another both at the edge element RR and at the separating element RT by at least one securing element BR or BT.
In a second aspect, the present invention relates to an electrolysis cell E encompassing a cathode chamber KK divided by the dividing wall W from the adjacent chamber, which is the anode chamber KA or a middle chamber KM of the electrolysis cell E.
In a third aspect, the present invention relates to a process for producing an alkali metal alkoxide solution in the electrolysis cell E according to the second aspect of the invention.

摘要： A polyester is useful as a high viscosity base fluid. A method for its preparation involves isomerizing an alpha-olefin, epoxidizing an internal olefin, reacting an internal epoxide, and isolating the polyester. Lubricant compositions can contain such polyesters and the compositions are useful as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or as hydraulic oils.
