Abstract:
1. A process for producing fluoropolymer particles, comprising: preparing a solution or dispersion comprising a fluoropolymer dissolved or dispersed in a first solvent comprising a solvent which causes the fluoropolymer to swell in a degree of exceeding 50% such that the degree of swelling of the fluoropolymer by the first solvent is in a range of from 50 to 1,200% in the solution or dispersion; and mixing the solution or dispersion with a second solvent comprising a solvent which causes the fluoropolymer to swell in a degree of at most 50% such that the fluoropolymer is flocculated and forms fluoropolymer particles and the degree of swelling of the fluoropolymer by a mixture of the first solvent and second solvent is from 0 to 100% in the solution or dispersion, wherein the first solvent and second solvent satisfy W
