Abstract
Process for obtaining microporous laminar structures permeable to water vapor, based on polyurethane, characterized in that it comprises the steps of: a) applying polyurethane (ureas) dissolved in hygroscopic solvents, containing 0.1-20% by weight (referred to to the total amount of polyurethane) of siloxane sequences of the general structural formula ** (formula) ** (b) optionally exposing a water vapor atmosphere until gelation occurs; and (c) then introducing into coagulation baths where the solvent is removed by washing the microporous laminar structure that is formed.
