Abstract
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.
