Abstract:
A novel aqueous polymerization process for making fluoropolymer dispersions 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, polypropylene glycol, and/or polytetamethylene glycol with repeating units of 3 to 100. The process and fluoropolymer produced contain no fluorinated surfactant.
