<p>A process for industrially advantageously producing at low cost fluoropolymers of various structures having a fluorine content regulated to a desired value and derivatives of the polymers; and a useful use of the fluoropolymer derivatives. The process comprises the following polymerization step and the following fluorination step which follows the polymerization step. Polymerization step: the step of polymerizing a monomer β having one or more carbon-bonded fluorine atoms and one or more carbon-bonded hydrogen atoms or the step of copolymerizing the monomer β with a comonomer (j) coplymerizable with the monomer β. Fluorination step: a step in which a partially fluorinated polymer having carbon-bonded fluorine atoms and carbon-bonded hydrogen atoms is dissolved in a solvent for fluorination and then fluorinated in the liquid phase to replace one or more of the carbon-bonded hydrogen atoms of the partially fluorinated polymer with fluorine atoms.</p> |
