STRUCTURES A COUCHES POLYMERIQUES MULTIPLES

摘要

The invention concerns structures with multiple polymeric layers comprising a layer (A) based on at least a halogenated hydrocarbon polymer bound to a layer (C) based on at least an olefin polymer via a layer (B) containing 100 to 10 wt. % of at least a grafted olefin polymer and 0 to 90 wt. % of at least a halogenated hydrocarbon polymer, the grafted olefin polymer being obtained by grafting a polymerisable monomer, a functional oligomer or a functional telomer on a pre-activated olefin polymer. The invention also concerns a method for obtaining said structures and their use.
