Abstract: The present invention describes a process by which a coating which has dirt- and water-repellant properties can be applied non-permanently to any article. It is usual nowadays for articles to be provided with self-cleaning properties by generating, on the surface of the article, a surface structure made from elevations and depressions which have to have a certain height and a certain separation. This is usually achieved by impressing such structures, or by securing structure-forming particles by means of a carrier system. In this way the surfaces are provided with a permanent self-cleaning surface. If scratching, discoloration, or some other type of damage causes impairment of the surface or surface structure, this cannot be simply removed and reapplied, but instead the article then has to be retreated, freed from the surface structure by a complicated method, or disposed of. In contrast, the inventive coating can be removed again from the articles by relatively simple mechanical means.

Abstract: The invention relates to mesotubes and nanotubes (hollow fibers) having an inner diameter of 10 nm-50 &mgr;m and to a method for the production thereof. The hollow fibers can be produced by coating degradable materials with non-degradable materials, whereby the degradable materials are destroyed by thermal methods, for instance. The hollow fibers are used in separation technology, catalysis, micro-electronics, medical technology, material technology or in the clothing industry.

Abstract: The invention relates to a process for the production of molding compositions from a thermoplastic polycondensation resin susceptible to degradation at high temperature in the presence of H.sub.2 O, to which is admixed a second synthetic resin, present as an aqueous latex, at temperatures in the range of 150.degree.-300.degree. C. and under a pressure in the range of 1-100 bar under the effect of high shear forces, for a time sufficient to provide the desired molding composition without substantially degrading the polycondensation resin.
