| titleOfInvention | Preparation of hexafluoropropene oxide polymers |
| abstract | A perfluorodicarboxylic fluoride of the formula: F-CO-CF 2 -O-Rf-O-CF 2 -CO-Fnor perfluorodiketone of the formula: R 1 -CO-Rf-CO-R 1 nwherein Rf is a perfluoroalkylene group and R 1 isna C 1-8 perfluoroalkyl group is mixed with an alkali metalnfluoride in an aprotic polar solvent to form an initiatornsolution. Hexafluoropropene oxide is fed to the initiatornsolution for polymerization, obtaining difunctionalnhexafluoropropene oxide polymers of high purity. |
