Abstract

A process for producing a fluororesin improved in solubility in solvents or (meth)acrylic monomers. It comprises adding (a) a fluoroolefin, (b) malonic acid, a malonic monoester, or a malonic diester, and (c) a water-soluble free-radical polymerization initiator to water and emulsion-polymerizing the mixture.
