Abstract

See full text

The vinylidene-fluoride-based polymer composition according to the present invention comprises a vinylidene-fluoride-based polymer and a specific surfactant and contains no fluorinated surfactant, wherein the specific surfactant is contained in an amount of 10 ppm or larger but less than 100 ppm in terms of mass ppm of the solid components of the composition and has an HLB value of 10 or greater. The method for producing a vinylidene-fluoride-based polymer according to the present invention comprises emulsion-polymerizing specific monomers in an aqueous medium in the presence of a specific emulsifier and an initiator without using any fluorinated surfactant, the use amount of the emulsifier being 8.5 ppm or larger but less than 100 ppm in terms of mass ppm of the monomers.
