Process for preparing fluoropolymer |
摘要 |
The polymerization initiator-containing solution obtained by mixing a specific perfluorodicarboxylic acid fluoride (A) with CsF in an aprotic polar solvent with stirring to conduct reaction and thereby form a polymerization initiator (B) and then allowing the reaction solution to stand for not less than 72 hours at a temperature of 0 to 30° C. A polymerization initiator-containing solution comprises a specific polymerization initiator (B') and an aprotic polar solvent. The process for preparing a perfluoropolyether comprises polymerizing hexafluoropropylene oxide in the presence of the polymerization initiator-containing solution.
