The invention relates to a multi-layer structure including placed one against the other, at least one layer of fluoride polymer onto which at least one unsaturated monomer has been grafted by irradiation, and at least one layer of PVC. According to a 1 st form, the multi-layer structure may include in order placed against one another: possibly a layer of fluoride polymer; a layer of fluoride polymer grafted by irradiation; and layer of PVC. According to a 2 nd form, the multi-layer structure includes in order placed against one another: possibly, a layer of fluoride polymer; a layer of fluoride polymer grafted by irradiation; a layer of PVC; a layer of fluoride polymer grafted by irradiation; and possibly a layer of a fluoride polymer. According to a 3 rd form, the multi-layer structure includes in order placed against one another: a layer of PVC; a layer of fluoride polymer grafted by irradiation; a layer of PVC. Said structure may be shaped into films, bottles, tanks, containers, pipes and containers of all kinds. |
