    • A polyfluoroalkane carboxylic acid represented by the following general formula: CnF2n+1(CH2CF2)m(CF2CF2)l−1CF2COOM (M: an alkali metal, a NH4 group or H; n: an integer of 1 to 6; m: an integer of 1 to 4; and l: 1 or 2) can be produced by hydrolysis reaction of polyfluoroalkane carboxylic acid fluoride represented by the following general formula: CnF2n+1(CH2CF2)m(CF2CF2)l−1CF2COF , where its carboxylic acid salt can be formed as an alkali metal salt, or a NH4 salt. The polyfluoroalkane carboxylic acid (or its salt) can act as a surfactant having distinguished monomer emulsificability and latex stability when used as an emulsifying agent or as a dispersing agent for polymerization reaction of fluorine-containing monomers, or as an effective surfactant capable of enhancing the micelles solubility of fluorine-containing monomers such as vinylidene fluoride, etc., when used as an emulsifying agent or a dispersing agent for homopolymerization or copolymerization reaction of vinylidene fluoride.

    • A peroxide-crosslinkable fluorine-containing elastomer IS produced by subjecting a fluorine-containing olefin and a perfluoroalkyl divinyl ether monomer represented by the general formula: CF2═CF—[OCF2CF(CF3)]aO(CF2)bO[CF(CF3)CF2O]c—CF═CF2 wherein a+c is an integer of 0 to 4 and b is an integer of 2 or more, to a copolymerization reaction; wherein the perfluoroalkyl divinyl ether monomer is added for copolymerization separately before and after the copolymerization reaction starts, or the total amount thereof is added for copolymerization after the copolymerization reaction starts. A peroxide-crosslinked molded product of the obtained fluorine-containing elastomer exhibits high compression set characteristic, while reducing a decrease in breaking strength, a decrease in elongation at break or an increase in hardness.
