CA 2449239

The present invention relates to polymer films and a polymer membrane having an improved mechanical property profile produced therefrom, to a process for producing them and to their use. The polymer films, polymer membranes and separation membranes of the invention are produced from selected polymer raw materials and have excellent chemical, thermal and mechanical properties as are required for use as polymer electrolyte membranes (PEMs) in PEM fuel cells or in apparatuses for the filtration and/or separation of gases and/or liquids or for reverse osmosis.

La présente invention concerne des films polymères ainsi qu'une membrane polymère produite à partir desdits films, ainsi que des membranes de séparation dotées d'un profil de propriétés mécaniques amélioré, un procédé de production et un procédé d'utilisation desdits films. Les films polymères, les membranes polymère et les membranes de séparation conformes à l'invention sont produites à partir de matières premières polymères sélectionnées et possèdent des propriétés chimiques, thermiques et mécaniques remarquables lorsqu'elles sont nécessaires par exemple dans les applications du type membranes d'électrolytiques polymères dans les cellules électrochimiques-PEM ou dans les appareils de filtrage et/ou de séparation de gaz et/ou de liquides ou dans des osmoses inverses.
