METHOD OF REDUCING METAL CONTENT IN FLUOROELASTOMER

摘要

A method of producing a fluoroelastomer reduced in the content of metallic ingredients; and a molded article comprising a fluoroelastomer sufficiently reduced in the content of metallic ingredients. The method comprises producing a fluoroelastomer without using a metal oxide through fluoromonomer polymerization, coagulation, and drying, wherein at least one of the starting materials excluding gaseous monomers contains substantially no metallic ingredients. The fluoroelastomer obtained by this method has a metal content of 50 ppm or lower.
