| titleOfInvention | Fluororesin, method for producing same, and method for producing fluororesin particles |
| abstract | The present invention relates to a fluororesin including a residue unit represented by a following general formula (1) and having a haze value equal to or less than 2% of a heat-press molded product (thickness 1 mm) with a small haze value of a melt-molded product and a method for producing the same.In the formula (1), Rf<sub>1</sub>, Rf<sub>2</sub>, Rf<sub>3</sub> and Rf<sub>4</sub> each independently represent one of the groups consisting of a fluorine atom, a linear perfluoroalkyl group having 1 to 7 carbon atoms, a branched perfluoroalkyl group having 3 to 7 carbon atoms, and a cyclic perfluoroalkyl group having 3 to 7 carbon atoms, the perfluoroalkyl group may have an ethereal oxygen atom, Rf<sub>1</sub>, Rf<sub>2</sub>, Rf<sub>3</sub> and Rf<sub>4</sub> may be linked to each other to form a ring having 4 or more and 8 or less carbon atoms, and the ring may include an ethereal oxygen atom. The present invention further relates to a method for producing fluororesin particles that each include a fluorine-containing aliphatic ring structure. The method comprises a precipitation step of lowering a solution temperature of a fluororesin (A) solution in which a fluororesin (A) including a fluorine-containing aliphatic ring structure is dissolved in a solvent (B), to precipitate particles of the fluororesin (A). The method is excelling in productivity and making it possible to remove foreign matter. |
