    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.

    摘要： The present invention relates to a method of producing the fluoropolymer according to any one of Claims 1 to 3, by subjecting a fluoropolymer precursor containing acid/acid salt groups and having -CF 2 COOX groups at polymer chain terminals, in the formula X represents H, NR 11 R 12 R 13 R 14 or M 4 1/L ; R 11 , R 12 , R 13 and R 14 are the same or different and each represents H or an alkyl group containing 1 to 4 carbon atoms and M 4 represents a metal having a valence of L, said metal having a valence of L being a metal belonging to the group 1, 2, 4, 8, 11, 12 or 13 of the long-form periodic table, to heat treatment for the conversion of said -CF 2 COOX groups to -CF 2 H groups, X being as defined above, wherein said fluoropolymer precursor is one obtained by polymerizing a perhalovinyl ether derivative represented by the general formula (I): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCF 2 =CF-O- (CF 2 CFY 1 -O) n - (CFY 2 ) m -SO 2 Z€ƒ€ƒ€ƒ€ƒ€ƒ(I) wherein Y 1 represents F, Cl or a perfluoroalkyl group, n represents an integer of 0 to 3, the n atoms/groups of Y 1 are the same or different, Y 2 represents F or Cl, m represents an integer of 1 to 5, the m atoms of Y 2 are the same or different and Z represents F, Cl, Br, I, -OM 5 1/L or -ONR 15 R 16 R 17 R 18 ; M 5 represents a metal having a valence of L and the metal having a valence of L is as defined above, and R 15 , R 16 , R 17 and R 18 are the same or different and each represents H or an alkyl group containing 1 to 4 carbon atoms, when the group -SO 2 Z in the general formula (I) is not said acid/acid salt group but is a group convertible to such acid/acid salt group, said fluoropolymer precursor is one subjected to a conversion treatment, after the above-mentioned polymerization, for the conversion of said group -SO 2 Z to the above-mentioned acid/acid salt group, and said heat treatment comprises heating said fluoropolymer precursor at 120 to 400°C.
