Polymer mixture and films prepared therefrom

A process for producing a waterproof, water vapor permeable, wind resistant textile composite material comprising combining a film and a textile material;

• wherein, the film is water vapor permeable and waterproof, and is produced from a polymer mixture comprising:
• constituent (A) 50 to 85 wt. % of a polyether block amide consisting of 30 to 60 wt. % of polyamide-12, polyamide-11 and/or polyamide-12,12 blocks and 70 to 40 wt. % of polyethylene glycol blocks,
• constituent (B) 10 to 40 wt. % of a polyether block amide consisting of 65 to 85 wt. % of polyamide-12, polyamide-11 and/or polyamide-12,12 blocks and 35 to 15 wt. % of polyethylene glycol blocks, and
• constituent (C) 5 to 40 wt. % of a poly(ethylene-co-vinylacetate-g-maleic anhydride) polymer consisting of 75 to 95 wt. % of ethylene monomer, 5 to 25 wt. % of vinylacetate monomer and 0.1 to 2 wt. % of maleic anhydride monomer,
• wherein the wt. % for the constituents (A), (B) and (C) are based upon the total amount of polymer mixture and the wt. % for the blocks making constituents (A) and (B), and the monomers making constituent C are based upon the weight of the constituent.
