    Abstract: Provided is a method for producing an aqueous dispersion of a fluorine-containing elastomer, comprising polymerizing a fluorine-containing monomer in the presence of a fluorine-containing compound (1) represented by general formula (1) and an aqueous medium to produce an aqueous dispersion of a fluorine-containing elastomer:


    CX1X2═CX3—Z  General formula (1):

    wherein X1 to X3 are each independently H, F, or a fluorine-containing alkyl group; when X1 and X2 are both H, X3 is F or a fluorine-containing alkyl group; Z is a group represented by —COOM, —SO3M, —OSO3M, —PO(OM)2, —OPO(OM)2, —BO(OM)2, or —OBO(OM)2; M is H, a metal atom, NR14, optionally substituted imidazolium, optionally substituted pyridinium, or optionally substituted phosphonium; and R1 is independently H or an organic group, and any two R1 are optionally bonded to each other to form a ring.

    Abstract: Provided is a member to be compressed for an electrochemical device obtained by crosslinking a crosslinkable composition containing a fluorine-containing elastomer, wherein the fluorine-containing elastomer exhibits a difference δG′ (G′(100° C.)−G′(180° C.)) between the storage elastic modulus G′(100° C.) at a measurement temperature of 100° C. and the storage elastic modulus G′(180° C.) at a measurement temperature of 180° C., in the dynamic viscoelasticity test (strain amplitude: 0.5 Deg; frequency: 100 CPM) with a rubber process analyzer satisfying the following conditions: 40 kPa
