Abstract
Procedure for obtaining microporous laminar structures, permeable to water vapor, by dissolving A) 90 to 70 parts by weight (based on the dry substance) of one or more polyurethanes free of nco groups, obtained by reacting essentially linear polyhydroxy compounds, not miscible with water, with oh groups in the final position and a molecular weight between 500 and 5000, and diols of low molecular weight with diisocyanate, which are soluble in strongly polar solvents, and B) 10 to 30 parts by weight (based on the dry substance) of one or more cationic, mainly linear, high molecular weight polyurethanes, free of nco groups, containing 8 to 30% by weight of urethane groups, and given case, urea groups, and 0.5 to 2.0% by weight of quaternary ammonium nitrogen atoms, the cationic polyurethane mass being presented as an aqueous dispersion or colloid solution and the concentration of the dispersion or solution being so large, so that the amount of water introduced by it into the finished mixture is less than 7% by weight, in C) 200 to 2000 parts by weight of a water-soluble solvent, strongly polar, for a) with a boiling point higher than 100º c, preferably with the simultaneous presence of a low-boiling solvent, D) where the solution, if appropriate after shaping, is allowed to gel in moist air, then the solvent is washed off with water or with a solvent/non-solvent mixture and where appropriate, E) before the gelation of the solution, at least 2.5% by weight (as dry substance referred to dry substance b) of anionic synthetic tanning agents, which have been obtained essentially from arylsulfonylic acids, if any substituted, are added, arylcarboxylic acids, phenols and formaldehyde, optionally with sulfuric acid or its salts and furthermore, with compounds that react with formaldehyde in known manner, or the finished lamellar structures of components a) and b) are further treated with an aqueous solution of these synthetic tanning agents, Characterized in that a product a) whose content of urethane -nh-co-o- groups is between 6 and 20% and whose nco/oh ratio in the synthesis is between 0.99 and 1.15 is used, especially between 1.01 and 1.09, the product a) solvent-free having a tensile strength of at least 100 kp/cm2, a shore a hardness between 35 and 90, and a plasticizing point greater than 100º c.
