Novel metallohalopolymers comprising an oxyhalopolymer and a transition metal covalently bonded to an oxygen site on the oxyhalopolymer possess desirable properties of inertness, stability, hydrophobicity and high electronegativity like fluoropolymers such as PTFE. The metallohalopolymers also possess unusual superacidic properties making oxygen-containing sites on the polymeric backbone highly nucleophilic and reactive with transition metals for synthesis of stable metallized polymers without requiring exposure to destructive calcining temperatures or intermediate chelating organosilane linking agents. The transition metals can be covalently bonded directly to the polymeric support to form metallohalopolymers for use as catalysts in the synthesis of chemicals, biocides and useful articles of manufacture, such as filtration devices containing the biocidally active metallohalopolymers.
A metallohalopolymer, which comprises a halogenated polymer having an outer surface modified with hydrogen and oxygen or oxygen-containing groups substituted for at least a portion of the halogen atoms thereon to provide an oxyhalopolymer, the oxygen or oxygen-containing groups on said oxyhalopolymer modified with an amount of covalently bonded transition metal on the outermost surface of said oxyhalopolymer and to depths of up to about 200 .ANG. to provide a surface having catalytic activity related to that of the particular transition metal, wherein the bulk characteristics of the halogenated polymer are retained below the modified outer surface region of the metallohalopolymer.
A metallohalopolymer, which comprises an oxyhalopolymer prepared from a halogenated polymer, said oxyhalopolymer selected from the group consisting of an oxyfluoropolymer and an oxychlorofluoropolymer, said oxyhalopolymer having an outer surface modified wherein from about 1 to about 100 percent of the oxygen or oxygen-containing groups of the outermost surface and to depths ranging from about 10 to about 200 .ANG. have covalently bonded thereto a transition metal or covalently bonded conductive metallic film.
A metallohalopolymer comprising a halogenated polymer with an oxyhalopolymer outer surface and a transition metal covalently bonded directly to a reactive oxygen site on said oxyhalopolymer.
A method of synthesizing metallohalopolymers which comprises the steps of:
