METHOD FOR PRODUCING FLUORINE-CONTAINING COPOLYMER LATEX FLUORINE-CONTAINING COPOLYMER LATEX BINDER FOR ELECTRODE PRODUCTION ELECTRODE MIXTURE FOR ELECTRICITY STORAGE DEVICES AND ELECTRODE FOR ELECTRICITY STORAGE DEVICES

摘要

Provided is a method for producing a fluorocopolymer latex in which the content of the metal component is small and the content of the organic solvent is at least good in stability of the latex. A monomer mixture containing tetrafluoroethylene and propylene is subjected to emulsion polymerization at a polymerization temperature in the range of 50 to 100 占 폚 in the presence of an aqueous medium, an anionic emulsifier and a thermally decomposable radical polymerization initiator to obtain a fluorocopolymer A method for producing a latex, wherein the aqueous medium comprises water alone or water and a water-soluble organic solvent, the content of the water-soluble organic solvent is less than 1 part by mass with respect to 100 parts by mass of water and the amount of the anionic emulsifier By weight based on 100 parts by weight of the fluorine-containing copolymer.
