Abstract (en)
[origin: WO2015019027A1] The invention relates to a multilayer structure which comprises a metal inner layer, preferably comprising at least 80% of zinc, intended for forming an anti-corrosion barrier, an outer layer consisting of a polyolefin as well as an intermediate layer made of a polyolefin that is not an elastomer, characterised in that the intermediate layer, which is in direct contact with the aforementioned inner and outer layers, includes a single functional polyolefin consisting of an ethylene terpolymer - alkyl-anhydride (meth)acrylate or unsaturated carboxylic acid. The invention also relates to a use of said intermediate layer for zinc metal pipes as a binder, as well as to a method for manufacturing such pipes, which are suitable in particular for transporting liquid.
