| titleOfInvention | Process for the manufacture of polyol perfluoropolyether derivative |
| abstract | The invention pertains to a process for the manufacture of a polyol (per)fluoropolyether derivative [polyol PFPE (PFPE-OH)], said process comprising: 1. reacting at least one triol having two protected hydroxyl functions and a free hydroxyl group [protected triol (PT)] with an activating agent, to yield an activated protected triol [activated protected triol (APT)]; 2. reacting said activated protected triol with a functional (per)fluoropolyether derivative of formula (Ia) [functional PFPE (E)], wherein: Rf represents a fluoropolyoxyalkene chain (chain Rf), i.e. 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, -CF2CI, -CF2CF2CI, -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 [protected polyol PFPE (p-PFPE-OH)]; 3. deprotecting said protected polyol PFPE (p-PFPE-OH) to yield the polyol PFPE (PFPE-OH). |
