摘要： In polymerizing hexafluoropropene oxide (HFPO) into a fluorinated polyether, a liquefied gas of fluorocarbon having 1 to 4 carbon atoms is added to a reactor. HFPO is polymerized in the reactor while maintaining a gas phase in the reactor under a pressure lower than the vapor pressure of the liquefied gas and allowing the liquefied gas to evaporate from the polymerization system. Heat of polymerization can be efficiently removed from the HFPO polymerization system of high viscosity, and the polymerization temperature is kept low.
