HYDROFLUOROALCOHOLS WITH IMPROVED THERMAL AND CHEMICAL STABILITY

摘要

Hydrofluoro alcohols of formula : A-(Rf)a-CFX-O-RhO-(CFX-(Rf)a*-CFX-O-RhO-)nH (I) 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 chosen from -F, -C1 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 chosen from -F, -C1 and -H.
