Liquid fluorine-containing polymer and a process for the production thereof.

摘要

A process for producing a readily crosslinkable liquid fluorine-containing polymer having a narrow molecular weight range distribution and containing iodine in the molecule in an amount of from 1 to 30% by weight based on the weight of the polymer, which process 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.lx wherein Rf is a saturated perfluorocarbon group, a saturated perfluorochlorocarbon group or a saturated fluorohydrocarbon group and x is an integer at least 1 corresponding to the bonding valency of Rf, whilst maintaining the proportion of the mole number of the monomeric components (M) to the mole number of the iodinated compound (I) in the range of from 10 to 1,200.
