<P>PROBLEM TO BE SOLVED: To provide a polymeric reaction reagent introducing a functional group such as a sulfonic acid group, a phosphonic acid group, a carboxylic acid group, a benzimidazole group, an imidazole group, a pyrazole group or a benzopyrazole group without reversibly dissociating even at high temperatures into an aromatic ring contained in a hydrocarbon or a fluorine polymer while maintaining oxidation resistance. <P>SOLUTION: A fluorinated ketone compound is represented by general formula (XCF<SB>2</SB>CFY)<SB>2</SB>CO. A method for producing the fluorinated ketone compound comprises reacting an alkali metal salt QM with a fluorinated olefin CF<SB>2</SB>=CFY and a carbonyl compound COW<SB>2</SB>(wherein, meanings of symbols in the chemical formulae are shown in the notes). <P>COPYRIGHT: (C)2004,JPO |
