Abstract
The present invention is aimed to provide a highly-productive method for producing a stabilized fluoropolymer. The present invention relates to a method for producing a stabilized fluoropolymer, comprising the step of bringing a fluoropolymer to be treated into contact with a fluorinating agent to produce a stabilized fluoropolymer, while maintaining the concentration of hydrogen fluoride present in a reaction vessel at not higher than 1.0% by volume.
