Title
(EN) GAS SEPARATION MEMBRANE
(FR) MEMBRANE DE SÉPARATION DE GAZ
(JA) 気体分離膜
Abstract
(EN) The present invention pertains to a gas separation membrane having as the main component thereof a polyacetal having 1.5-10 mol of oxyalkylene units relative to 100 mol of oxymethylene units. This gas separation membrane has good carbon dioxide gas separation performance and a high permeation speed, and is suitable as a gas separation membrane for carbon dioxide in exhaust gas.
(FR) La présente invention concerne une membrane de séparation de gaz ayant, comme composant principal de celle-ci, un polyacétal ayant 1,5-10 moles d'unités oxyalkylène par rapport à 100 moles d'unités oxyméthylène. Cette membrane de séparation de gaz a une bonne performance de séparation de dioxyde de carbone gazeux et une vitesse élevée de perméation et est appropriée comme membrane de séparation de gaz pour du dioxyde de carbone dans un gaz d'échappement.
(JA)  本発明は、オキシメチレンユニット100molに対してオキシアルキレンユニットが1.5~10molであるポリアセタールを主成分とする気体分離膜に関する。本発明の気体分離膜は、炭酸ガス分離能及び透過速度が高く、排ガス中の炭酸ガス分離膜として好適である。
