abstract |
The invention refers to new compounds of the formulanR 6 R 7 CFSO 2 R 8 , wherein R 6 is perfluoroalkyl, perfluoroalkylncontaining one or more ether oxygen atoms, perfluoroalkoxy ornperfluoroalkoxy containing one or more ether oxygen atoms, R 7 nis perfluoroalkyl or perfluoroalkyl containing one or morenether oxygen atoms, and R 8 is perfluoroalkyl. The compoundsnare useful as initiators for the copolymerization of tetrafluoroethylenenand hexafluoropropylene to yield amorphousnpolymers. |
