A process for producing an elastic fluorocopolymer, by emulsion-polymerizing at least one fluoromonomer (a), a vinyl ester monomer (b) represented by the formula CR.sup.1R.sup.2.dbd.CR.sup.3COOCH.dbd.CH.sub.2 optionally, at least one hydrocarbon monomer (c) selected from the group consisting of ethylene, propylene and a vinyl ether, in an aqueous medium to produce an elastic fluorocopolymer latex, adjusting the pH of the elastic fluorocopolymer latex to from 1 to 9, and coagulating the elastic fluorocopolymer latex to isolate an elastic fluorocopolymer.
