Abstract
A process for preparing a membrane comprising applying a curable composition to a porous support and curing the composition, wherein the composition comprises: a) a curable ionic compound; b) a first crosslinking agent; c) a second crosslinking agent; d) an inert solvent; and e) optionally a free radical initiator; wherein the second crosslinking agent has a melting point below 80° C. Also claimed are the compositions and membranes obtainable by using the process.
