Abstract
A composition includes a perfluorinated propenylamine represented by the following general formula (1): Each occurrence of Rf1 and Rf2 is: (i) independently a linear or branched perfluoroalkyl group having 1-8 carbon atoms and optionally comprises one or more catenated heteroatoms; or (ii) bonded together to form a ring structure having 4-8 carbon atoms and that optionally comprises one or more catenated heteroatoms. At least 60 wt. % of the perfluorinated propenylamine is in the form of the E isomer, based on the total weight of the perfluorinated propenylamine in the composition.
