Title: PRODUCTION METHOD FOR FLUOROPOLYMER, SURFACTANT FOR POLYMERIZATION, AND USE OF SURFACTANT
Abstract:
The purpose of the present invention is to provide a novel production method for a fluoropolymer. This production method for a fluoropolymer includes a step in which a fluoropolymer is obtained by polymerizing a fluoromonomer in an aqueous medium in the presence of a surfactant. The production method for the fluoropolymer is characterized in that the surfactant is at least one surfactant selected from the group consisting of surfactants represented by the formula R1a-CO-R2a-CO-R3a-OSO3Xa, and surfactants represented by R1b-CO-(CR2b2)n-(OR3b)p-(CR4b2)q-L-OSO3Xb.
