摘要： The present invention aims to provide a method of producing a fluoropolymer, especially a fluoropolymer essentially including a tetrafluoroethylene or chlorotrifluoroethylene unit, at a higher polymerization rate with improved efficiency, the method being capable of improving the moldability in extrusion molding and suppressing discoloration. The method of producing a fluoropolymer of the present invention includes producing a fluoropolymer by polymerizing tetrafluoroethylene or chlorotrifluoroethylene in the presence of a peroxydicarbonate. The peroxydicarbonate is represented by the formula: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR-O-C(=O)-O-O-C(=O)-O-R wherein R's may be the same as or different from each other and individually represent a C4 alkyl group or alkoxy alkyl group.

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 aims to provide an ETFE film having excellent transparency and heat resistance and cost efficiency. The present invention relates to a film including a copolymer containing an ethylene unit, a tetrafluoroethylene unit, and a (fluoroalkyl)ethylene unit represented by Formula (1): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCH 2 =CX-Rf€ƒ€ƒ€ƒ€ƒ€ƒ(1) wherein X represents H or F, and Rf represents a fluoroalkyl group having 2 or more carbon atoms, the copolymer containing the (fluoroalkyl)ethylene unit in an amount of 0.8 to 2.5 mol% relative to the amount of all the monomer units and containing the ethylene unit and the tetrafluoroethylene unit at a molar ratio of 30.0/70.0 to 50.0/50.0, the film having a crystallinity of 68% or less, the crystallinity being calculated on the basis of a diffraction intensity curve of the film resulting from X-ray diffraction measurement.
