| titleOfInvention | Process for recovering fluoropolymers |
| abstract | A process for recovering fluoropolymers, which comprises contacting an ion exchange membrane comprising a fluoropolymer having carboxylic acid groups (hereinafter referred to as a C-polymer) and a fluoropolymer having sulfonic acid groups (hereinafter referred to as a S-polymer) and having inorganic particles deposited on the surface, with a solvent which is a good solvent for the C-polymer and a good solvent for the S-polymer, to separate a solution having the C-polymer and the S-polymer dissolved therein, and the inorganic particles, then esterifying the C-polymer in the solution to form precipitate of an ester of the C-polymer, and fractionating and recovering the precipitate and a solution having the S-polymer dissolved therein by solid-liquid separation. |
