摘要： The invention provides a powder that is easily redispersible in a liquid medium such as water. The powder contains a fluoropolymer. The fluoropolymer contains at least one group A selected from the group consisting of - SO 2 Y, -COOR, -SO 3 X, -SO 2 NR 1 2 , and -COOX, wherein Y is a halogen atom; R is a C1-C4 alkyl group; X is M 1/L or NR 1 4 , where M is a hydrogen atom or an L-valent metal, the L-valent metal being a metal in group 1, group 2, group 4, group 8, group 11, group 12, or group 13 of the periodic table; and R 1 s are each individually a hydrogen atom or a C1-C4 alkyl group. The powder exhibits a dispersion of 50% or higher. The dispersion is calculated by filtering a composition obtainable by mixing the powder with water through a mesh having an opening of 20 µm.
