Abstract
(EN)
This composite hollow fiber membrane comprises a gas-permeable non-porous homogeneous layer which has a polyolefin resin (A) as the main component and a porous support layer which is made of a polyolefin resin (B) and which supports said non-porous homogeneous layer, and the composite hollow fiber membrane is characterized in that the polyolefin resin (A) of non-porous homogeneous layer is a block copolymer of ethylene units and at least one type of olefin unit selected from α-olefin units having a carbon number of 3-20. By this means, a gas-permeable composite hollow fiber membrane is provided which has good gas permeability, reduces the impact of condensate on the performance of a gas dissolving module, and has excellent elution properties.

La présente invention concerne une membrane composite à fibres creuses comprenant une couche homogène non poreuse perméable au gaz qui comporte une résine de polyoléfine (A) en tant que constituant principal et une couche de support poreuse constituée d'une résine de polyoléfine (B) et supportant ladite couche homogène non poreuse. Selon l'invention, la membrane composite à fibres creuses est caractérisée en ce que la résine de polyoléfine (A) de la couche homogène non poreuse est un copolymère à blocs d'unités éthylène et d'au moins un type d'unité oléfine choisi parmi des unités α-oléfine ayant un nombre d'atomes de carbone de 3 à 20. dePar ce moyen, on obtient une membrane composite à fibres creuses perméable au gaz ayant une bonne perméabilité au gaz, réduisant l'impact de condensat sur la performance d'un module de dissolution de gaz et présentant d'excellentes propriétés d'élution.
