Production method for polytetrafluoroethylene aqueous dispersion |
| abstract |
The present invention aims to provide a method of producing a fluoropolymer aqueous dispersion having a significantly small particle size and excellent dispersion stability without using a long-chain fluorosurfactant. The present invention relates to a method of producing an aqueous dispersion containing at least one fluoropolymer selected from the group consisting of polytetrafluoroethylene and melt-processible fluororesins excluding polytetrafluoroethylene. The method includes polymerizing a fluoromonomer in an aqueous medium in the presence of a fluorosurfactant having a Log POW value of not higher than 3.4 and a polymerization initiator. The amount of the fluorosurfactant corresponds to 4600 to 500000 ppm of the aqueous medium. |
