Title (EN) GAS SEPARATION MEMBRANES COMPRISING CROSSLINKED CELLULOSE ESTERS
(FR) MEMBRANES DE SÉPARATION DE GAZ COMPRENANT DES ESTERS DE CELLULOSE RÉTICULÉS
Abstract:
(EN) This patent application discloses membranes comprised of cellulose esters that are crosslinked. The membrane can be in the form of a flat film, tube or hollow fiber membrane. The membranes are plasticization resistant and can be used to separate gases.
(FR) Cette demande de brevet concerne des membranes constituées d'esters de cellulose qui sont réticulés. La membrane peut se présenter sous la forme d'un film plat, d'un tube ou d'une membrane à fibres creuses. Les membranes sont résistantes à la plastification et peuvent être utilisées pour séparer des gaz.
