Title (EN) COMPOSITE POLYAMIDE MEMBRANE DERIVED FROM CARBOXYLIC ACID CONTAINING ACYL HALIDE MONOMER
(FR) MEMBRANE DE POLYAMIDE COMPOSITE DÉRIVÉ D'ACIDE CARBOXYLIQUE CONTENANT UN MONOMÈRE HALOGÉNURE D'ACYLE
Abstract: front page image
(EN)A method for making a composite polyamide membrane comprising the step of applying polyfunctional amine and acid halide monomers to a surface of a porous support and interfacially polymerizing the monomers to form a thin film polyamide layer. The method further includes the step of conducting the interfacial polymerization in the presence of: a carboxylic acid monomer comprising an aliphatic or aromatic moiety substituted with single carboxylic acid functional group and at least one acyl halide functional group, and a tri-hydrocarbyl compound.
(FR)Procédé de fabrication d'une membrane de polyamide composite comprenant une étape consistant à appliquer une amine polyfonctionnelle et des monomères halogénure d'acide sur la surface d'un support poreux pour former une couche mince de polyamide. Le procédé comprend en outre une étape consistant à réaliser la polymérisation interfaciale en présence d'un monomère acide carboxylique comprenant une fraction aliphatique ou aromatique substituée par un seul groupement fonctionnel acide carboxylique et au moins un groupement fonctionnel halogénure d'acyle, et un composé trihydrocarbyle.
