Abstract
Abstract Fluorinated phosphonic acid compounds, useful as treatments for substrate surfaces, have the formula: wherein: R 1 is a straight chain alkylene group having from about 3 to about 21 carbon atoms, an oxa-substituted straight chain alkylene group having from about 2 to about 20 carbon atoms, or a thia-substituted straight chain alkylene group having from about 2 to about 20 carbon atoms; R 2 is a perfluoroalkyl group having from about 4 to about 10 carbon atoms; R 3 is hydrogen, an alkali metal cation, or an alkyl group having from about 1 to about 6 carbon atoms; and M is hydrogen or an alkali metal cation, with the proviso that if R 1 is an unsubstituted straight chain alkylene group, then the sum of carbon atoms in R 1 and R 2 combined is at least 10.
