フルオロポリマーの製造方法、重合用界面活性剤及び界面活性剤の使用

Document Type and Number:

Japanese Patent JP6780774

Kind Code:

B2

Abstract:

The invention aims to provide a novel method for producing a fluoropolymer. The method for producing a fluoropolymer of the invention includes polymerizing a fluoromonomer in an aqueous medium in the presence of a surfactant to provide a fluoropolymer. The surfactant includes at least one selected from the group consisting of a surfactant represented by R^1a-CO-R^{2 a}-CO-R^{3 a}-A^a and a surfactant represented by R^1b-CO-(CR^2b₂)_n-(OR^3b)_p-(CR^4b₂)_q-L-Ab.
