| 主权项 | 1. A membrane obtained by a process comprising the following steps: applying a curable composition to a support; and curing the composition to form a membrane; wherein the curable composition comprises: (i) 7.47 to 43.33 wt % crosslinker comprising at least two acrylamide groups;(ii) 20 to 65 wt % curable ionic compound comprising an ethylenically unsaturated group and an anionic group;(iii) 15 to 45 wt % solvent; and(iv) 0 to 10 wt % of free radical initiator; wherein the molar ratio of (i):(ii) is from 0.1 to 1.5. | ||
