    Abstract: A process for the manufacture of a polyol (per)fluoropolyether derivative, comprising: 1. reacting at least one triol having two protected hydroxyl functions and a free hydroxyl group with an activating agent, to yield an activated protected triol; 2. reacting the activated protected triol with a functional (per)fluoropolyether derivative of formula: T2-O—Rf-T1, wherein: Rf represents a fluoropolyoxyalkene chain which is a fluorocarbon segment comprising ether linkages in main chain; T1 and T2, equal to or different from each other, are independently selected from non-functional groups of formula: —CF3, —CF2—CF3, —CF2Cl, —CF2CF2Cl, —CF2—COF, —COF: and functional hydroxyl groups comprising at least one hydroxyl group, with the provisio that at least one of T1 and T2 is a functional hydroxyl group as above detailed to yield a protected polyol (per)fluoropolyether derivative; and 3. deprotecting the protected polyol (per)fluoropolyether derivative to yield the polyol (per)fluoropolyether derivative.
