Document Type and Number:

WIPO Patent Application WO/2023/243729

Kind Code:

A1

Abstract:

The present invention provides a method for producing a perfluoroelastomer, wherein a perfluoroelastomer is produced by polymerizing tetrafluoroethylene (1) and a perfluoromonomer (2) other than the tetrafluoroethylene (1) within a reaction container. With respect to this method for producing a perfluoroelastomer, the volume of water and a fluorine-containing solvent in the inner volume of the reaction container is 2.0% by volume or less.
