Abstract
Procédé de fabrication de membranes perméables. Il consiste à mélanger à l'état fondu A une résine synthétique thermoplastique pouvant être étirée avec B un composé partiellement compatible avec cette résine et choisi parmi des polymères ou oligomères synthétiques ou des polymeres naturels en C20 au moins, des acides gras en C16 au moins et leurs esters ou sels, à mettre le mélange fondu sous la forme d'une feuille, à faire passer la masse fondue à travers une zone chauffée 6 maintenue à une température supérieure à la température de déformation à chaud des composants A et B, puis à la refroidir et à la solidifier, en réglant la durée comprise entre la formation de la feuille fondue et sa solidification; à traiter l'article obtenu avec un solvant qui est un solvant médiocre du composant A et un bon solvant du composant B; et à le sécher.
