Production Principle Of Perfluororubber

Emulsion polymerization of perfluoro(methyl vinyl) ether, tetrafluoroethylene and a small amount of perfluoroalkene ether with peroctanoic acid saddle as dispersant and ferric persulfate-sodium sulfite as initiator at a pressure of 1.4~4.2MPa and a temperature of 40~100 degrees Celsius Obtained, use diamine or 2,2'-bis(4-phenyloxypropane) and fluorine on the perfluorobenzene ring to undergo double nucleophilic substitution and sulfide.
