Beschreibung
Zusammenfassung:	Provided is a fluoropolymer composition production method for producing a fluoropolymer composition comprising a fluoropolymer, the method comprising polymerizing a fluoromonomer in a reactor in the presence of a fluorine-containing surfactant, a polymerization initiator, and an aqueous medium to prepare an aqueous dispersion comprising a fluoropolymer; after the aqueous dispersion is prepared, removing from the reactor the fluoromonomer remaining in the reactor, or recovering the aqueous dispersion in the reactor and accommodating the aqueous dispersion in a container different from the reactor; adding a radical generator to the aqueous dispersion; and subjecting to a heat treatment the aqueous dispersion comprising the radical generator to give a fluoropolymer composition.
