Title:
フルオロポリマー水性分散液の製造方法
Document Type and Number:
Japanese Patent JP6369541
Kind Code:
B2
Abstract:
The present invention provides a method for producing a fluoropolymer aqueous dispersion having a significantly small particle size and excellent dispersion stability. The present invention relates to a method for producing an aqueous dispersion containing at least one fluoropolymer selected from the group consisting of polytetrafluoroethylene and melt-fabricable fluororesins excluding polytetrafluoroethylene. The method includes polymerizing a fluoromonomer in an aqueous medium in the presence of a fluorosurfactant and a polymerization initiator. The fluorosurfactant has a concentration in the aqueous medium of not lower than 0.8 times the critical micelle concentration of the fluorosurfactant.
