ABSTRACT:
To provide a method of reducing contents of metal components of a fluorine-containing elastomer through preparation thereof and a molded article obtained from the fluorine-containing elastomer having sufficiently reduced contents of metal components. The method of reducing a metal content of the fluorine-containing elastomer through preparation thereof without using a metal oxide, in which among materials excluding a gaseous monomer which are used for polymerization of a fluorine-containing monomer, coagulation and drying, at least one of them contains substantially no metal component, and the fluorine-containing elastomer which has a metal content of not more than 50 ppm and is obtained by that method.
