METHOD FOR PRODUCING FLUORINE-CONTAINING POLYMER, AQUEOUS DISPERSION OF FLUORINE-CONTAINING POLYMER, 2-ACYLOXYCARBOXYLIC ACID DERIVATIVE, AND SURFACE ACTIVE AGENT

摘要

The present invention provides a method of producing a fluoropolymer, wherein polymerization using a carboxylate ester bond-containing carboxylic acid derivative as a surfactant in an aqueous medium to give the fluoropolymer is conducted, the above carboxylate ester bond-containing carboxylic acid derivative has a carboxylate ester bond and -COOM (M representing H, NH 4 , Li, Na or K), the above carboxylate ester bond may optionally be substituted by fluorine atom.
