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