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