Abstract: The invention relates to a process for the production of a multilayered composite element which comprises a layer of leather, a layer of a hard component formed from a polymer, which is bonded to the leather layer in certain areas, and a layer of a soft component, which is arranged between the leather component and the hard component, which comprises laying the leather against one mold surface of a mold, positioning the soft component on the leather, and molding the polymer acting as hard component onto the leather layer and the soft component layer at a pressure of at least 50 bar, preferably greater than 100 bar, in particular greater than 180 bar, and at a temperature of greater than 100° C., preferably from 180 to 280° C., in particular from 200 to 250° C., by bonding the leather and the hard component to one another in certain areas at least, with temperature of the mold surface of the mold being controlled, at least during the bonding. The invention furthermore relates to a composite element obtainable by the process. The composite element is extremely robust, has a soft touch surface and is inexpensive to produce.

Abstract: Statistical propylene copolymers with 2-10C alk-1-ene comonomer (alkene) units are claimed, obtained by polymerisation of propylene and alkene at 50-100 degrees C and 15-40 bar with a mean residence time of 0.5-5 hrs., in presence of a Ziegler-Natta catalyst with: (a) a titanium-containing solid component containing a magnesium compound, a halogen, a silica gel support and a carboxylate ester as electron donor; plus (b) an aluminium compound; and (c) another electron donor as cocatalysts. The silica gel support has an average particle diameter of 5-200 mu m and an average primary particle diameter of 1-10 mu m, and contains 5-20 vol% of pores or channels with an average diameter of 1-10 mu m. Also claimed is a process for the production of propylene copolymers.

Abstract: A semifinished leather product is produced from an animal hide by pretanning with the use of a chromium-free tanning agent and of a clay mineral which, after stirring for 30 minutes in water at 50° C. at a circumferential rotor speed of from 5 to 25 m/s, has a number average particle diameter of less than 2 μm or a bimodal particle size distribution with a first, finely divided fraction whose number average particle diameter is less than 0.5 μm and a second, coarser fraction whose number average particle diameter is less than 5 μm, determined in each case by the method according to ISO 13320-1, by combined laser light diffraction and light scattering, a proportion of the first, finely divided fraction being from 10 to 90% by weight, and drying of the pretanned animal hide to a water content of from 5 to 45%, based on the total weight of the semifinished leather product.

Abstract: The present invention relates to fuel-water emulsions which use an alkoxylated, preferably ethoxylated, polyisobutene as the emulsifying agent. Stable emulsions, especially of diesel-water mixtures, which are provided wi th advantageous characteristics when being used as fuel in internal combustion engines can thus be produced.
