Abstract:
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.
