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.
摘要翻译： 在将六氟丙烯氧化物（HFPO）聚合成氟化聚醚的过程中，将碳氟化碳碳氢化合物的液化气体加入到反应器中。 将HFPO在反应器中聚合，同时在低于液化气体的蒸汽压力的压力下保持反应器中的气相，并允许液化气体从聚合系统蒸发。 可以从高粘度的HFPO聚合体系中有效地除去聚合热，聚合温度保持不变。
