1. Perfluorinated aminoether compositions comprising perfluoroaminoethers having two or more tertiary amino nitrogen atoms each of which is connected to the other(s) adjacent thereto by (1) a catenary, ether oxygen-containing perfluoroalkylene linking group, the catenary carbon atoms of which are in the form of perfluoroalkylene segments of carbon atoms that are 2 to 4 in number, said segments having up to 5 carbon atoms, (2) a catenary ether oxygen-containing perfluorocyclohexylene linking group, or (3) a catenary ether oxygen-containing linking group having said perfluoroalkylene segments and perfluorocyclohexylene moieties, the sum of the catenary ether oxygen atoms in said linking groups being 1 to 3 and each of the terminal amino nitrogen atoms having bonded thereto two perfluoroalkyl radicals.
