A fluoropolymer solid composition which contains a fine particle comprising a fluoropolymer, said fluoropolymer having an acid/acid salt group, said acid/acid salt group being a sulfonic acid group, -SO2NR17R18, a carboxyl group, -SO3NR1R2R3R4, -SO3M1 1/L, -COONR5R6R7R8 or -COOM2 1/L (in which R17 and R18 are the same or different and each represents a hydrogen atom, an alkali metal, an alkyl group or a sulfonyl-containing group, R1, R2, R3 and R4 are the same or different and each represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, R5, R6, R7 and R8 are the same or different and each represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, M1 and M2 are the same or different and each represents a metal whose valence is L, and said metal whose valence is L is a metal belonging to the group 1, 2, 4, 8, 11, 12 or 13 of the periodic table); said fine particle comprising the fluoropolymer containing, at the proportion of at least 25% by mass thereof, a spherical fluoropolymer fine particle, and said spherical fluoropolymer fine particle being substantially spherical.
La présente invention concerne une composition de fluoropolymère solide contenant de fines particules d'un fluoropolymère, caractérisée en ce que le fluoropolymère renferme des groupes acides ou acidobasiques, les groupes acides ou acidobasiques étant sulfo, -SO2NR<17>R<18>, carboxy, -SO3NR<1>R<2>R<3>R<4>, -SO3M<1>1/L, -COONR<5>R<6>R<7>R<8>, ou COOM<2>1/L (où R<17> et R<18> sont les mêmes ou différents et chacun représente un hydrogène, un métal alcalin, un alkyle ou un groupe contenant un sulfonyle; R<1>, R<2>, R<3> et R<4> sont les mêmes ou différents et chacun représente un hydrogène ou un alkyle C1-4; R<5>, R<6>, R<7> et R<8> sont les mêmes ou différents et chacun représente un hydrogène ou un alkyle C1-4; et M<1> et M<2> sont les mêmes ou différents et chacun représente un métal possédant une valence L, le métal de valence L appartenant au groupe 1, 2, 4, 8, 11, 12 ou 13 du tableau périodique), et en ce que les fines particules de fluoropolymère comprennent au moins 25 % en poids de fines particules de fluoropolymère sensiblement sphériques.
