  • Emulsion polymerization of fluoropolymers using europium III chloride
    Patent number: 8394882
    Abstract: An improved process for emulsion polymerization of fluoropolymers, such as polytetrafluoroethylene, employs reduced amounts of fluorinated emulsifiers. The addition of europium III chloride facilitates emulsion polymerization of fluoropolymers having comparable quality to those fluoropolymers made using conventional processes employing greater amounts of environmentally undesirable fluorinated emulsifiers.
    Type: Grant
