A composite membrane for use as an ion-exchange membrane includes a conducti ve polymer and a support material for the polymer, said polymer having a moiety of formula (I) and/or a moiety of formula (II) and/or a moiety of formula (III), wherein at least some of the units I, II and/or III are functionalize d to provide ion exchange sites; wherein the phenyl moieties in units I, II, a nd III are independently optionally substituted and optionally cross-linked; an d wherein m, r, s, t, v, w and z independently represent zero or a positive integer, E and E' independently represent an oxygen or a sulphur atom or a direct link, G represents an oxygen or sulphur atom, a direct link or a -O-P h- O- moiety where Ph represents a phenyl group and Ar is selected from one of the following moieties (i)*, (i) to (x) which is bonded via one or more of i ts phenyl moieties to adjacent moieties. |
