Document Type and Number:
Japanese Patent JP2009526934
Kind Code:
A
Abstract:
The present invention relates to a structure comprising a substrate and at least one first layer applied to the substrate and made of a thermoplastic composition comprising at least one functionalized polyolefin obtained either by copolymerization or by grafting of a polyolefin backbone with an unsaturated monomer comprising an anhydride, acid or epoxide function, said functionalized polyolefin being grafted with polyether units comprising a terminal amine, by means of reactive extrusion, as a breathable waterproof material having a water vapor permeability of at least 300 g/m2 24 h−1 measured according to the standard ASTM E96, method BW (38° C./50% relative humidity), for a film of 25 μm. It also relates to the use of such a composition as a breathable waterproof material having a water vapor permeability of at least 300 g/m2 24 h−1 (measured according to the standard ASTM E96, method BW 38° C./50% relative humidity), for a film of 25 μm.
