摘要：
The present invention provides the fluorine-containing elastic copolymer which is excellent in molding processability, particularly molding stability and further vulcanization properties, flowability at molding and compression set of a vulcanized rubber. The copolymer is prepared through emulsion polymerization of vinylidene fluoride and at least one of other monomers in two polymerization stages by using a water-soluble radical polymerization initiator in a very small amount of 0.001 to 0.03% by weight based on the total weight of copolymers prepared in the two stages and an oil-soluble radical polymerization initiator. The present invention also provides a process for preparation thereof and a vulcanizable composition containing the same.
