Summary: | Hydrofluoro alcohols of formula (I): A-(Rf)a-CFX-O-RhO-(CFX-(Rf)a*-CFX-O-RhO-)nH in which: Rh is a hydrocarbon-based chain; X is F or a C1-C6 (per)fluoroalkyl; a or a* is 0 or 1; Rf is a (per)fluoro(poly)oxyalkylene chain or a (per)fluoroalkyl chain; A is selected from the group consisting of -F, -Cl, and -H (possible only when a=1) or is HO-Rh-O-CFX-; n is an integer from 0 to 200, with the condition that n=0 when A is selected from the group consisting of -F, -Cl, and -H. |
