| 摘要 |
The present invention relates to a process for preparing a fluoropolymer containing at least one kind of fluoroolefin, which comprises carrying out polymerization in the presence of a surfactant represented by the formula (1):
(wherein R 1 and R 2 may be the same or different respectively, and represent an alkyl group or an alkenyl group, R 3 is a hydrogen atom, an alkyl group or an alkenyl group, the total carbon number of R 1 to R 3 is 2 to 25, L- is a group represented by -SO 3 -, -OSO 3 -, -PO 3 -, -OPO 3 - or -COO-, and M + is a monovalent cation). Thereby, polymerization can be carried out with excellent production efficiency in the presence of a small amount of a surfactant, and a fluoropolymer can be prepared without lowering various physical properties such as water resistance by the surfactant.
