ABSTRACT:
An epoxy or trimethylene ether-direct grafted halogeneated vinyl polymer is prepared by the reaction of an epoxide such as a 5-ethyl, 5'-methyl-hydantoin/epichlorogydrin 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 is grafted directly to the first carbon-chain carbon of the halogenated vinyl polymer. The graft polymer compositions are utilized as ultrafiltration and reverse osmosis membranes.
