Abstract
A curable composition comprising the components (i) 0 to 60 wt % non-ionic crosslinker(s); (ii) 20 to 85 wt % curable ionic compound(s) comprising an anionic group and at least one ethylenically unsaturated group; (iii) 15 to 45 wt % solvent(s); (iv) 0 to 10 wt % of photoinitiator(s); and (v) 2 to 45 wt % of structure modifier(s); wherein the molar ratio of component (v):(ii) is 0.25 to 0.65. The compositions are useful for preparing membranes for (reverse) electrodialysis.
Claims23
A process for preparing a membrane comprising the following steps:
- (i) applying a curable composition to a support;
- and
- (ii) curing the composition to form a membrane;
- wherein the curable composition comprises the components:
- (i) 0 to 60 wt % non-ionic crosslinker(s);
- (ii) 20 to 85 wt % curable ionic compound(s) comprising an anionic group and at least one ethylenically unsaturated group;
- (iii) 15 to 45 wt % solvent(s);
- (iv) 0 to 10 wt % of photoinitiator(s);
- and
- (v) 2 to 45 wt % of structure modifier(s) selected from the group consisting of polyvalent metal salts and organic compounds comprising at least two groups selected from amino and quaternary ammonium groups;
- wherein the molar ratio of component (v):(ii) is 0.25 to 0.65.
