Abstract (en)
[origin: WO2007093745A2] The invention relates to a structure comprising a substrate and at least one first layer applied to the substrate made from a thermoplastic composition with at least one functionalised thermoplastic obtained by copolymerisation or grafting of a polyolefin backbone with an unsaturated monomer with an anhydride, acid or epoxide function, the functionalised polyolefin being grafted by polyether groups with a terminal amine by means of reactive extrusion. Said structure is a breathable waterproof material with water vapour permeability of at least 300 g/m<SUP>2</SUP>24 h<SUP>-1</SUP> measured by the standard ASTM E96, method BW (38°C/50 % relative humidity), for a film of 25 µm. The invention further relates to the use of such a composition as a breathable waterproof material with water vapour permeability of at least 300 g/m<SUP>2</SUP>24 h<SUP>-1</SUP> measured by the standard ASTM E96, method BW (38°C/50 % relative humidity), for a film of 25 µm.
