Beschreibung
Zusammenfassung:	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 polymer (1) containing a polymerization unit (1) based on a monomer (1) represented by general formula (1) and an aqueous medium, CF2=CF-R-CZ1Z2-COOM (1)wherein R is a linking group, Z1 and Z2 are each independently F or CF3, and M is H, a metal atom, NR74, imidazolium optionally having a substituent, pyridinium optionally having a substituent, or phosphonium optionally having a substituent, wherein R7 is H or an organic group.
