Process for producing fluorine-containing acrylic or methacrylic polymers

摘要

A process for producing a fluorine-containing acrylic or methacrylic polymer, comprises polymerizing a fluorine-containing acrylate or methacrylate in a solution phase formed of an organic solvent and dissolved therein a monomer containing a fluorine-containing acrylate or methacrylate having a polyfluoroalkyl group having 6 to 16 carbon atoms. A non-halogen type solvent is used as the organic solvent and the fluorine-containing acrylate or methacrylate is so polymerized that a polymer-containing liquid phase comprised of the fluorine-containing acrylic or methacrylic polymer formed with progress of polymerization and the organic solvent is separated from the solution phase. This process enables production of a fluorine-containing acrylic or methacrylic polymer having a fluorine monomer in a high proportion by the use of a commonly available general-purpose solvent, without using any fluorine type solvent.
