摘要: Interfacially polymerized, crosslinked membranes on microporous, organic solvent resistant ultrafiltration membrane backing are useful for the separation of mixtures under reverse osmosis conditions. The prepared by depositing an aqueous (or conversely non-aqueous) solution a first component microporous backing, draining off excess quantity this and then applying second in form non-aqueous aqueous) solution. two components interact polymerize at interface between phase to produce highly thin polymer layer support layer.
