Method for producing fluorine-containing polymer and fluorine-ion exchange membrane |
| abstract |
By using a polymerization medium having a low ozone depletion coefficient or a global warming coefficient and a small chain transfer constant, a fluorine-containing polymer having high molecular weight and excellent heat resistance, solvent resistance, and chemical resistance is efficiently produced. In the method for producing a fluorine-containing polymer in which a fluorine-containing monomer having a carboxylic acid type functional group and a fluorine-containing olefin are polymerized using a hydrofluorocarbon as a medium, the hydrofluorocarbon as the polymerization medium has 4 to 10 carbon atoms. And the ratio of the number of hydrogen atoms / number of fluorine atoms (based on moles) (H / F ratio) is 0.05 to 20. |
