Membrane from epoxy-direct grafted halogenated vinyl polymer |
| abstract |
A membrane useful as an ultrafiltration or reverse osmosis membrane is formed from the casting onto a substrate such as a porous polyester sheet a material comprising an epoxy- or trimethylene ether-direct grafted halogenated vinyl polymer prepared by the reaction of an epoxide such as a 5-ethyl,5'-methyl-hydantoin/epichlorohydrin condensation product with a halogenated vinyl polymer such as polyvinylidene fluoride in the presence of a metal halide catalyst. The ether residue of the epoxide or trimethylene-containing group is grafted directly to the first carbon-chain carbon of the halogenated vinyl polymer. |
