    • PROBLEM TO BE SOLVED: To provide a fluororubber copolymer containing PMVE (perfluoromethyl vinyl ether) units and excellent in resistances to chemicals and cold. SOLUTION: This fluororubber copolymer is prepared by radical polymerization in the presence of a diiodide compound represented by general formula (1): RI 2 (wherein R is a 1-16C saturated fluorohydrocarbon or chlorofluorohydrocarbon group or a 1-3C hydrocarbon group), contains 40-70mol% vinylidene fluoride units, 10-25mol% tetrafluoroethylene units, and 20-35mol% perfluoromethyl vinyl ether units, and contains iodine in a quantity of 0.05-2wt.% based on the quantity of the copolymer. The copolymer after vulcanization exhibits a TR70 of -20 to -30°C in the TR test according to ASTM D1329; and its rate of volume change after the immersion in a liquid mixture comprising fuel C/methanol in a wt. ratio of 15/85 at 40°C for 70hr is 8-18%.
