AI Technical Summary
Existing methods for producing fluorine-containing elastomers using hydrocarbon surfactants result in significant polymer deposits on the polymerization tank and require long reaction times.
A method involving emulsion polymerization of fluorine-containing monomers in an aqueous medium with a fluorine-containing compound containing a functional group capable of radical polymerization and a hydrophilic group, in the presence of a hydrocarbon surfactant, while omitting fluorine-containing surfactants, to produce a fluorine-containing elastomer with reduced tank adhesion and shorter reaction times.
The method enables the production of the desired amount of fluorine-containing elastomers in a short period of time with minimal polymer deposits on the polymerization tank and improved stability of the aqueous dispersion, resulting in elastomers with excellent vulcanization properties and molded articles.
