1. A membrane formed from a material comprising an epoxide modified halogenated vinyl polymer formed by contacting an epoxy-direct grafted halogenated vinyl polymer wherein an ether moiety of an epoxy-direct grafted group is bonded directly to a first carbon-chain carbon of a halogenated vinyl polymer, said first carbon-chain carbon being adjacent to a second carbon-chain carbon of the halogenated vinyl polymer, said second carbon-chain carbon bonded directly with two moieties selected from the group consisting of fluoro, chloro, bromo, iodo, methyl and hydro, provided that said second carbon-chain carbon has bonded directly thereto at least one fluoro, chloro, bromo or iodo moiety.
