Abstract

Une membrane semi-perméable convenant pour être utilisée dans un rein artificiel du type à filtration est produite en préparant une solution d'acétate de cellulose dans un mélange solvant consistant essentiellement en un solvant de l'acétate de cellulose et en un agent de gonflement, et en étalant la solution sur un substrat, le solvant étant un mélange de diméthylformamide et d'acétone, l'agent de gonflement étant un mélange de cyclohexanone et d'eau, le rapport en poids du diméthylformamide et de l'acétone à l'agent de gonflement se situant dans la zone délimitée par les quatre points A (60, 20, 20), B (35, 35, 20), C (25, 35, 40) et D (50, 10, 40) des coordonnées triangulaires représentées sur la figure unique, le rapport de la cyclohexanone à l'eau étant compris entre 0,8 et 1,3.
