ABSTRACT:
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.
