Process for producing fluoropolymer by ring-opening polymerization of fluorinated epoxy compound

摘要

There is provided a polymer having electrical/optical functions attributed to the stability of a C-F bond in addition to chemical stability by efficiently polymerizing a fluorinated epoxy compound. A process for producing a fluoropolymer having two or more units of a repeating unit represented by the following formula (2), which comprises ring-opening polymerization of a fluorinated epoxy compound represented by the following formula (1) in the presence of a trialkylaluminum and a salt having an organic cation as a counter cation: wherein Q represents a single bond or a bivalent linking group containing no fluorine atom; RF represents a monovalent organic group containing a fluorine atom; and * indicates that the carbon atom marked with * is an asymmetric carbon atom.
