The invention relates to a drawn polymer film, comprising (A) a polymer or polymer blend and at least (B) one additional component with an average particle diameter of between 0.1 and 15 µm, which by means of (C) one or several secondary treatment steps is processed to form a membrane after being drawn. The average particle diameter of component (B) ranges between 0.1 and 15 µm, preferably 0.5 - 8.0 µm, with the range between 1.0 and 7.0 µm being particularly preferred. The membranes are used for alkene-alkane separation, electrodialysis, the desalinisation of seawater, in fuel cell applications and other membrane applications.
La présente invention concerne un film polymère étiré, comprenant (A) un polymère ou un mélange de polymères, et au moins (B) un autre constituant d'un diamètre de particules moyen compris entre 0,1 et 15 µm, lequel constituant est soumis à (C) une ou plusieurs étapes de traitement ultérieur, de manière à former une membrane après avoir été étiré. Le diamètre de particules moyen du constituant (B) est compris entre 0,1 et 15 µm, de préférence entre 0,5 et 8 µm et au mieux entre 1,0 et 7 µm. Ces membranes sont utilisées dans la séparation des alcènes/alcanes, l'électrodialyse, le dessalement d'eau de mer, dans des applications de piles à combustible et d'autres applications de membranes.
