Abstract
(EN)
Disclosed is a composite separation membrane having excellent chemical resistance, separation performance and water permeability at the same time. The separation membrane has a separation function layer formed on a porous supporting membrane, and is characterized in that the separation function layer contains at least a polymer of a polyhedral silsesquioxane represented by general formula (a) and a hydrophilic monomer. (R1SiO1.5)n(R2SiO1.5)m (a) (In the formula, R1 includes a polymerizable reactive moiety; R2 represents a hydrogen atom or an alkyl group, which may be substituted; and n and m each represents an integer satisfying n ≥ 2 or m ≥ 0, with n + m being 8, 10 or 12.)
(FR)
L'invention porte sur une membrane de séparation composite ayant à la fois d'excellentes propriétés de résistance aux produits chimiques, d'efficacité de séparation et de perméabilité à l'eau. La membrane de séparation, qui a une couche fonctionnelle de séparation formée sur une membrane support poreuse, est caractérisée par le fait que la couche fonctionnelle de séparation contient au moins un polymère d'un silsesquioxane polyèdre représenté par la formule générale (a) et un monomère hydrophile. (R1SiO1,5)n(R2SiO1,5)m (a) (Dans la formule, R1 comprend une fraction réactive polymérisable ; R2 représente un atome d'hydrogène ou un groupe alkyle, qui peut être substitué ; et n et m représentent chacun un entier satisfaisant à n ≥ 2 ou m ≥ 0, n + m étant de 8, 10 ou 12.)
