摘要：
A process for producing an elastic fluorocopolymer, by emulsion-polymerizing at least one fluoromonomer (a), a vinyl ester monomer (b) represented by the formula CR1R2═CR3COOCH═CH2 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.
