    • The present invention relates to a multilayer tube comprising, in its radial direction from the outside inwards: an outer layer formed from a polyamide, a layer formed from a copolyamide, a layer formed from an EVOH, a layer formed from a copolyamide, an inner layer formed from a polyamide, the layers being successive and adhering to one another in their respective contact region. Advantageously, the inner layer is formed by a compound based on a polyamide and electrically conducting carbon black, producing a surface resistivity of less than 106 Ω/?. The outside diameter of these tubes may range from 6 to 110 mm and the wall thickness may be from 0.5 to 5 mm. Advantageously, the petrol tube according to the invention has an outside diameter ranging from 6 to 12 mm and a total wall thickness of 0.36 mm to 1.95 mm, namely: a thickness of 50 to 700 μm for the polyamide outer layer, a thickness of 10 to 150 μm for the copolyamide layers, a thickness of 10 to 200 μm for the EVOH layer, a thickness of 100 to 500 μm for the polyamide inner layer possibly filled with electrically conducting carbon black. The tube of the present invention has a very low permeability to petrol, particularly to hydrocarbons and their additives, and in particular to alcohols, such as methanol and ethanol, or to ethers, such as MTBE or ETBE. These tubes also have good resistance to engine lubrication oils and fuels.

    • The present invention relates to a method for radiation grafting a compound by irradiation, that can be grafted onto a fluoropolymer, so as to prevent destabilization of the fluorinated polymer. Said method comprises the following steps: a) the fluoropolymer is mixed in the melted state thereof with a graftable compound; b) the mixture obtained in a) is converted into films, plates, granulates or powder; c) the products from step b) are subjected to photonic (γ) or electronic (β) irradiation in a dose of between 0.5 and 15 Mrad; and d) optionally, the products from step c) are washed and/or a degassed. According to said method, a stabilizing agent is added to the fluorinated polymer. Said stabilizing agent can be an antioxidant, a graftable metal salt, or a combination of the two. The invention also relates to structures comprising at least one layer of said mixtures and at least one layer of another material, and to the use of said structures to obtain a barrier effect. Said structures act as a barrier to a plurality of fluids, especially to petrol and to air-conditioning fluids, and can take the form of bottles, tanks, containers, pipes, and all kinds of recipients. They can also be transformed into films used to produce packaging.
