Document Type and Number:
WIPO Patent Application WO2002062567
Kind Code:

Abstract:
The invention concerns in a first embodiment a structure comprising successively: a first polyolefin layer, an optional binding layer, and a second fluorinated polymer layer. The binder layer may be based on hydrogenated three-block copolymer ABC, or may comprise several layers: an optional layer (L1) comprising a fluorinated polymer and a polymer essentially consisting of alkyl (meth)acrylate units, a layer (L2) based on polyamide with amine ends and a layer (L3) consisting of a polyolefin functionalised with an unsaturated carboxylic acid anhydride, the layer (L3) being in contact with the polyolefin layer. Said structures are useful for making devices for transporting and storing fluids.
