  A fluoroelastomer is produced by the polymerization reaction of a fluorinated olefin using a ωH perfluorocarboxylic acid represented by the general formula: H(CF2)nCOOM (wherein M is hydrogen atom, alkali metal, or ammonium group; and n is 6, 7, or 8) or a salt thereof, as an emulsifier. The fluoroelastomer produced by the method of the present invention has a low Mooney viscosity ML1+10(121°C) and thereby has an improved fluidity, which is essential for injection molding materials, as a result of the polymerization reaction of a fluorinated olefin using a ωH perfluorocarboxylic acid (salt) as an emulsifier. Accordingly, the productivity in injection molding can be improved. Moreover, there is neither remarkable decrease in the polymerization rate of the polymerization reaction nor deterioration of the physical properties of the vulcanizate, such as tensile strength, compression set characteristics, and hot tear resistance.

  氟橡胶是由氟化烯烃与通式为 H(CF2)nCOOM（其中 M 为氢原子、碱金属或铵基团；n 为 6、7 或 8）的ωH 全氟羧酸或其盐进行聚合反应而制得：H(CF2)nCOOM（其中 M 为氢原子、碱金属或铵基团；n 为 6、7 或 8）或其盐作为乳化剂。用本发明的方法生产的氟橡胶具有较低的门尼粘度 ML1+10(121°C)，因此具有较好的流动性，这对于注塑成型材料来说是至关重要的，这是以 ωH 全氟羧酸（盐）为乳化剂的氟化烯烃聚合反应的结果。因此，可以提高注塑成型的生产率。此外，聚合反应的聚合速率既没有明显下降，硫化胶的物理性质（如拉伸强度、压缩永久变形特性和抗热撕裂性）也没有恶化。
