Abstract:
1. A fluorochemical nitrogen-containing diketone compound comprising: a first terminal, branched perfluoroalkylcarbonyl group having from 3 to 10 in-chain carbon which can include, optionally, one or more in-chain oxygen atoms; at least one linear, branched, or cyclic perfluoroalkylene segment having 4 or more in-chain carbon or nitrogen atoms attached to the first terminal, branched perfluoroalkylcarbonyl group, said perfluoroalkylene segment containing one or more in-chain tertiary nitrogen atoms; and a second terminal, branched perfluoroalkylcarbonyl group having from 3 to 10 in-chain carbon atoms which can include, optionally, one or more in-chain oxygen atoms, wherein the second perfluoroalkylcarbonyl group is attached to the perfluoroalkylene segment.
