Abstract
PURPOSE: To obtain a fluorine-containing elastic polymer having improved physical properties and processability, by copolymerizing vinylidene fluoride and other fluorine-containing monomer under specific conditions.
CONSTITUTION: Vinylidene fluoride is copolymerized with one or more other fluorine-containing nonomers, e.g. tetrafluoroethylene, in the presence of an inorganic free radical polymerization initiator in an aqueous medium at a radical formation rate R(m mole/l-min) of 1.0W3.5×10-2 and 1.5×10-2W2.5×10-5 in the period about 10% of the total polymerization time after the initiation and about 10% before the termination respectively. The R 10% before the termination is preferably 1/10 or less of that 10% after the initiation, and the ratio of the number of moles (Mp) of monomers to that (ΔI) of decomposed initiator per 5min is changed from 10W100 to 3,000W200,000.
