  • Patent number: 8871332
    Abstract: Disclosed is a fluorine-containing polymer obtained by polymerizing a 1,6-diene-type ether compound represented by formula [1] and, for example, a (meth)acrylic acid compound represented by formula [2]. The fluorine-containing polymer shows high transparency, has a high glass transition point, and is soluble in a solvent and therefore has moldability. In the case where a (meth)acrylic unit has a reactive substituent, by utilizing the crosslinking reaction thereof, a thin film having high solvent resistance can be produced. In formulae [1] and [2], R1 and R2 each independently represent a hydrogen atom or an alkyl group having 1 to 12 carbon atoms, which may be substituted, R3 represents a hydrogen atom, a fluorine atom, or a methyl group, and R4 represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, which may be substituted, or an aromatic group having 5 to 10 ring members, which may be substituted.

  • Patent number: 8778691
    Abstract: A method for measuring bromate ion is provided that provides high-sensitivity measurement results more simply and more quickly than conventional bromate ion measurement methods. A fluorescent substance that is quenched by coexistence with bromate ions is added to a sample 130 and the fluorescence intensity of the fluorescent substance after quenching is measured, the measured fluorescence intensity being subtracted from the fluorescence intensity of a standard sample containing no bromate ions to calculated the fluorescence intensity difference. The bromate ion concentration is calculated from the calculated fluorescence intensity difference, using a pre-determined calibration line between the fluorescence intensity difference and the bromate ion concentration.
