The present invention provides sulfur containing fluoroalkyl amines represented by the formula Rf-Q-S(O)x-C(H)i(CH3)j-(CH2)z+(i-1)-NHR and isocyanate/isothiocyanate derivatives thereof represented by the formula Rf-Q-S(O)x-C(H)i(CH3)j-(CH2)z+(i-1)-N=C=X1 wherein Rf is chosen from a C2-C12 perfluoroalkyl provided that: i) one fluorine atom of the perfluoroalkyl can be optionally replaced by hydrogen, and/or ii) the perfluoro-alkyl can be optionally interrupted by at least one oxygen, methylene, or ethylene; Q is chosen from the group consisting of a C2-C12 hydrocarbylene optionally interrupted by at least one divalent organic group; x is 1 or 2; z is 0 or 1; i is 1 or 2; j is 0 or 1; provided that i+j=2; R is chosen from H or a C1 to C4 alkyl; and X1 is O or S.
