Estimating the term…
A fluororesin including a residue unit of formula (1) and having a haze value equal to 2% or less 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. Rf1, Rf2, Rf3 and Rf4 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, Rf1, Rf2, Rf3 and Rf4 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.
A method for producing fluororesin particles, wherein each fluororesin particle comprises a flourine-containing aliphatic ring structure, the method comprising:
