Abstract
There is provided the process for effectively preparing the fluorine-containing polymer without using CFC and HCFC which have a high polymerization rate and a high ozone depletion potential and a coating film having excellent mechanical properties, solvent resistance and chemical resistance can be formed using the obtained fluorine-containing polymer. In preparing the fluorine-containing polymer by polymerizing a monomer containing a fluoroolefin in a polymerization medium, the fluorine-containing solvent having an ozone depletion potential of 0 and a solubility of hydroxybutyl vinyl ether of not less than 0.5% is used as the polymerization medium.
