Abstract
A novel aqueous polymerization process for making fluoropolymers is disclosed in which non-ionic non-fluorinated emulsifier is used to produce fluoropolymer emulsions. The emulsifiers used in the invention are those that contain segments of polyethylene glycol and/or polypropylene glycol with repeating units of 3 to 100.
