Process for producing fluoroelastomers

A novel emulsion polymerization process for the production of fluoroelastomers is disclosed wherein a hydrocarbon sulfonate anionic surfactant of the formula CH3-(CH2)n-SO3M, CH3-(CH2)n-C6H4-SO3M, or CH3-(CH2)n-CH=CHCH2-SO3M, where n is an integer from 6 to 17, or mixtures thereof, and M is a cation...

Summary:A novel emulsion polymerization process for the production of fluoroelastomers is disclosed wherein a hydrocarbon sulfonate anionic surfactant of the formula CH3-(CH2)n-SO3M, CH3-(CH2)n-C6H4-SO3M, or CH3-(CH2)n-CH=CHCH2-SO3M, where n is an integer from 6 to 17, or mixtures thereof, and M is a cation having a valence of 1, is used as the dispersing agent.
