ABSTRACT:
A process for producing a readily crosslinkable liquid, fluorine-containing polymer having a narrow range of molecular weight distribution and containing iodine in the molecule in an amount of 1 to 30% by weight based on the weight of the polymer, which comprises polymerizing vinylidene fluoride and at least one other fluoroolefin in the presence of a radical-producing source and an iodinated compound of the formula: Rf/I.sub.x wherein Rf is a saturated perfluorocarbon group, a saturated perfluorochlorocarbon group or a saturated fluorochlorohydrocarbon group and x is an integer of not less than 1 corresponding to the bonding valency of Rf while maintaining the proportion of the mole number of the monomeric components (M) to the mole number of the iodinated compound (I) in a range between 10 and 1,200.
