Abstract
An organic polymeric material, which is preferably perfluorinated and which comprises a polymeric chain and at least one group pendant from the chain, in which the group pendant from the chain comprises a saturated cyclic group and at least one ion-exchange group or group convertible thereto, and in which the ion-exchange group or group convertible thereto is linked to the polymeric chain through the cyclic group. Also an ion-exchange membrane produced from the polymeric material, an electrolytic cell containing the membrane, vinyl monomers from which the organic polymeric material may be produced and intermediates useful in production of the monomers.
