摘要：
The invention aims to provide a novel method for producing a fluoropolymer. The method for producing a fluoropolymer of the invention includes polymerizing a fluoromonomer in an aqueous medium in the presence of a surfactant to provide a fluoropolymer. The surfactant includes at least one selected from the group consisting of a surfactant represented by R 1a -CO-R 2 a -CO-R 3 a -A a and a surfactant represented by R 1b -CO-(CR 2b 2 ) n -(OR 3b ) p -(CR 4b 2 ) q -L-Ab.
