摘要： A magnet wire including a conductor and an insulating coating formed on an outer periphery of the conductor. The insulating coating contains a copolymer containing a tetrafluoroethylene unit and a fluoroalkyl vinyl ether unit. The copolymer has a melt flow rate of 10 to 60 g/10 min, and the copolymer has a fluoroalkyl vinyl ether unit content of 6.2 to 8.0% by mass based on a total content of monomer units.

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: R—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.
