摘要: 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 contain blocks of polyethylene glycol, polypropylene glycol and/or polytetramethylene glycol. The process and fluoropolymer produced contain no fluorinated surfactant. The fluoropolymers have excellent resistance to discoloration.
