The disclosure provides a production method capable of producing a hollow fine particulate containing a fluorine-containing resin and having a large average particle size. The production method includes a step A of dispersing a solution containing a fluorinated monomer and a non-polymerizable solvent into water to provide a dispersion; a step B of polymerizing the fluorinated monomer to provide a phase-separated fine particulate containing a fluorine-containing resin; and a step C of removing the non-polymerizable solvent in the phase-separated fine particulate to provide a hollow fine particulate.

A primary object of the present disclosure is to provide: a fluoropolymer composition that has a low refraction index and that comprises a structural unit having a fluorine-containing aliphatic ring, the fluorine-containing aliphatic ring having one, two, or three ethereal oxygen atoms as ring-constituting atoms; a production method therefor; and the like. The present disclosure relates to a fluorine-containing composition comprising two or more fluorine-containing polymers (A), each containing as a main component a structural unit having a fluorine-containing aliphatic ring, the fluorine-containing aliphatic ring having one, two, or three ethereal oxygen atoms as ring-constituting atoms; and the like.

Disclosed herein are flame retardant compounds and polymer compositions containing these flame retardant compounds. The flame retardant compounds can be derived from biological sources and can include coordinated metal ions.

To provide a process for producing a fluorinated polymer having a cyclic structure at a relatively low cost, by efficiently recovering, from a mixture containing a fluorinated polymer obtained by polymerizing a perfluoromonomer having a cyclic structure and an unreacted perfluoromonomer having a cyclic structure, the unreacted perfluoromonomer having a cyclic structure. A monomer component containing a perfluoromonomer having a specific cyclic structure is polymerized in the presence of a polymerization initiator at a predetermined polymerization temperature to obtain a mixture containing a fluorinated polymer and an unreacted cyclic structure monomer, and the perfluoromonomer having a cyclic structure is recovered from the mixture at a temperature of at most the maximum ultimate temperature of the polymerization temperature+12 C. and at most the 10 hour half-life temperature of the polymerization initiator+12 C. under a pressure of less than the atmospheric pressure.
