    摘要: An object of the present invention is to provide a method for recovering a hydrofluorocarbon capable of recovering a hydrofluorocarbon used for producing fluoropolymers, in a higher recovery efficiency and in a shorter time. The present invention relates to a method for recovering a hydrofluorocarbon, including: producing a wet fluoropolymer by suspension polymerization, solution polymerization, or bulk polymerization in the presence of a hydrofluorocarbon; vaporizing and discharging vaporizable substances including the hydrofluorocarbon by heating the wet fluoropolymer in a container; and transferring the discharged vaporizable substances to a cooling means to cool the substances.
