Abstract

A method for producing a fluoropolymer which includes polymerizing a fluoromonomer in an aqueous medium in the presence of a surfactant to provide a fluoropolymer, the surfactant being represented by the general formula (1): CRRR—CRR—X-A, wherein Rto Rare each H or a monovalent substituent, with the proviso that at least one of Rand Rrepresents a group represented by the general formula: —Y—Rand at least one of Rand Rrepresents a group represented by the general formula: —X-A or a group represented by the general formula: —Y—R; and A is the same or different at each occurrence and is —COOM, —SOM, or —OSOM. Also disclosed is a surfactant for polymerization represented by the general formula (1), a method for producing a fluoropolymer using the surfactant, a composition including a fluoropolymer and the surfactant and a molded body including the composition.
