Abstract
Abstract Perfluoroaminoethers are provided. The perfluoroaminoethers have 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 segments of vicinal carbon atoms that are 2 to 4 in number, said segments having up to 5 carbon atoms, a catenary ether oxygen-containing perfluorocyclohexylene linking group, or (3) a catenary ether oxygen-containing linking group having perfluoroalkylene and perfluorocyclohexylene moieties, the sum of the catenary ether oxygen atoms being 1 to 6.
