Zusammenfassung:	PCT No. PCT/GB93/01472 Sec. 371 Date Dec. 22, 1994 Sec. 102(e) Date Dec. 22, 1994 PCT Filed Jul. 14, 1993 PCT Pub. No. WO94/03503 PCT Pub. Date Feb. 17, 1994A fluoroorganic polymeric material which comprises a polymeric chain and at least one group pendent from the polymeric chain, in which the group pendent from the polymeric chain comprises at least one ion-exchange group or group convertible thereto, wherein the EW distribution is greater than 1.05, and wherein the ion-exchange group or group convertible thereto is preferably linked to the polymeric chain through an acyclic secondary carbon atom, for use as an ion-exchange membrane in an electrochemical device.
