Abstract

PURPOSE: To prepare a fluorine-containing elastomer copolymer having excellent mechanical properties, resistance to aging, etc. and copolymerizable at low temperature, by copolymerizing fluorine-containing monomers in the presence of a Redox-type catalyst comprising hydrogen peroxide and ascorbic acid.
CONSTITUTION: A fluorine-containing elastomer copolymer is prepared by copolymerizing (A) two or more fluorine-containing monomers, e.g. hexafluoropropene, vinylidene fluoride, etc., in an aqueous medium at 5W50°C in the presence of (B) a Redox-type polymerization catalyst comprising (a) hydrogen peroxide and (b) L-ascorbic acid. The copolymerization in the aqueous medium is preferably the emulsion polymerization. Preferably the amount of (a) is 10-4W10mol% on the basis of (A) and the amount of (b) is 5W150mol% on the basis of (a).
