摘要：
A process for producing a perfluoropolymer, the process including extruding a polymer obtained by polymerizing a perfluoromonomer to prepare strands, and bringing a gas comprising from 3 to 50 volume % of fluorine gas into contact with the strands; the process being conducted on an apparatus that includes an extruder for melting and extruding the polymer obtained by polymerizing a perfluoromonomer, a die having a plurality of pores for preparing the strands from the molten polymer extruded, and a fluorination tank for bringing the gas comprising from 3 to 50 volume % of fluorine gas into contact with the strands.
