Abstract: A polymer material consisting of at least two layers, at least one fluorine-containing layer and at least one non-fluorine-containing layer, in which the fluorine-containing layer is 0.01 to 100 mu m thick, contains 0.1 to 0.76 g of fluorine per g of the fluorine-containing layer and coated with 40 mu g/cm to 50 mg/cm fluorine. Use of the polymer materials for the production of tanks, especially for fuel.

Abstract: A transition-metal catalyst component for a Ziegler catalyst system, obtainable by 1) mixing, in a solvent, an inorganic, oxidic carrier with 1.1) a vanadium trihalide/alcohol complex of the formula VY3nZ-OH, where Y is chlorine or bromine, N is from 1 to 6, and Z is a monovalent, saturated, aliphatic or araliphatic hydrocarbon radical having not more than 10 carbon atoms, and 1.2) a titanium trihalide or a titanium trihalide/aluminum trihalide complex, where the halogen can be chlorine and/or bromine, or a titanium trihalide complex of the formula TiY3. nZ-OH or a mixture thereof, where Y is chlorine or bromine, n is from 1 to 6, and Z is a monovalent, saturated, aliphatic or araliphatic hydrocarbon radical having not more than 10 carbon atoms or a mixture thereof, and 1.3) a zirconium tetrahalide, where the halogen can be chlorine and/or bromine, 2) removing the solvent by evaporation, 3) mixing the solid-phase intermediate from step (2) with 3.1) an organoaluminum catalyst component of the formula AlRmX3-m, where R is a C1- to C18 - hydrocarbon radical, m is from 1 to 3, and X is OR, chlorine, bromine or hydrogen, and 3.2) an organic carboxylate or an organosilicon compound or a mixture thereof in an organic solvent, and 4) if desired, isolating the solid-phase intermediate by filtration, washing and drying. and the use thereof for the homopolymerization or copolymerization of ethane are described.

Abstract: Hollow articles are made from stabilizer-free high-density polyethylene, e.g. by blow moulding a fuel container in the absence of oxygen. The absence of stabilizers, e.g. UV or heat stabilizers, is said to improve the barrier effect, or resistance to fuel permeability, long term, to which end the container may also be conventionally treated with a reactive gas, e.g. containing fluorine.

Abstract: Polybutylene terephthalate (PBT) is used as the barrier layer(s) (B) in a multilayer plastic composite material which also contains layer(s) (A) comprising mainly (at least 90 wt%) ethylene homo- or co-polymers and, if required, layer(s) of coupling agent (C) to promote adhesion between (A) and (B). Independent claims are also included for (a) a process for the production of this material by coextrusion-blow moulding; (b) hollow products made from this material, especially plastic fuel containers.
