Abstract
A rubber compound comprising a fluorine rubber component and an acrylic rubber component is produced by adding an acrylic monomer to an aqueous emulsion of fluorine-containing elastomer obtained by emulsion polymerization, using a fluorine-containing surfactant, followed by radical polymerization reaction. The obtained rubber compound can satify both of vulcanization moldability and heat aging resistance, and is at a lower cost than the expensive fluorine rubber.
