Abstract
Fluorophosphate containing an ethylene-tetrafluoroethylene moiety of formula (I) or (II):
(A)w-P(O)(O−M+)3-w (I) or
wherein
- A is Rf—(CH2)k—[(CF2CF2)y—(CH2CH2)z]mO and contains from about 8 to about 22 carbon atoms;
- Rf is CnF2n+1;
- n and k are each independently 1 to about 6;
- y, z, and m are each independently 1, 2, 3, or mixture thereof;
- w is 1 or 2 or a mixture thereof; and
- M is hydrogen, ammonium ion, an alkali metal ion, or an alkanolammonium ion,
- said fluorophosphate useful as a surfactant for altering the surface behavior of a liquid by addition thereto, and for providing surface effects to a substrate treated with a composition containing the fluorophosphate.
