Summary:Asymmetric hollow fiber membranes comprising a porous substrate layer and a skin layer are described. The skin layer is a copolymer of polymethyl pentene and polypropylene. Gas separation articles made using such hollow fiber membranes, as well as methods of making and using such hollow fiber membranes and gas separation articles are also described. L'invention concerne des membranes à fibres creuses asymétriques comprenant une couche de substrat poreuse et une couche de peau. La couche de peau représente un copolymère de polyméthylpentène et de polypropylène. L'invention concerne également des articles de séparation de gaz fabriqués au moyen de telles membranes à fibres creuses, ainsi que des procédés de fabrication et d'utilisation de telles membranes à fibres creuses et articles de séparation de gaz.
