The present invention aims to provide a production method that can produce an aqueous dispersion containing polyvinylidene fluoride with high productivity. The present invention relates to a method of producing an aqueous dispersion of polyvinylidene fluoride, including: emulsion polymerization of vinylidene fluoride in the presence of a surfactant, an organic peroxide, and water to produce an aqueous dispersion that contains polyvinylidene fluoride. The surfactant has a surface tension of 55 mN/m or smaller when added in an amount of 1000 ppm.
本发明的目的是提供一种生产方法,该方法能够以高生产率生产含有聚偏氟乙烯的水分散液。本发明涉及一种生产聚偏氟乙烯水性分散体的方法,包括:在表面活性剂、有机过氧化物和水的存在下,对偏氟乙烯进行乳液聚合,生产出含有聚偏氟乙烯的水性分散体。当表面活性剂的添加量为 1000 ppm 时,其表面张力为 55 mN/m 或更小。
