A liquid fluoropolymer composition which comprises a fluoropolymer and a film-forming aid, wherein the fluoropolymer comprises acid/acid salt type fluorovinyl ether units represented by the following general formula (I): and the film-forming aid is an organic liquid having compatibility with water and a boiling point of 100 to 300°C, excluding 100°C. The liquid fluoropolymer composition is a fluoropolymer dispersion composition comprising fine particles of the fluoropolymer and the film-forming aid and is characterized in that at least 25 wt.% of the fine fluoropolymer particles are accounted for by fine fluoropolymer particles which are substantially spherical. L'invention concerne une composition de fluoropolymère liquide qui contient un fluoropolymère et un auxiliaire filmogène, dans laquelle le fluoropolymère contient des unités éther fluorovinylique de type acide/sel acide représentées par la formule générale (I), et l'auxiliaire filmogène est un liquide organique ayant une compatibilité avec l'eau et un point d'ébullition de 100 à 300 DEG C, 100 DEG C exclus. La composition de fluoropolymère liquide est une composition à dispersion de fluoropolymère contenant de fines particules du fluoropolymère et l'auxiliaire filmogène, et elle est caractérisée en ce qu'au moins 25 % en poids de fines particules de fluoropolymère sont constitués de fines particules de fluoropolymère sensiblement sphériques.
