Abstract:
A process for the manufacture of a functional (per)fluoropolyether derivative comprising at least one triazole group, such process comprising: (1) reacting a (per)fluoropolyether hydroxyl derivative having at least one hydroxyl group [derivative (PFPE-OH)] with an activating agent, to yield an activated (per)fluoropolyether hydroxyl derivative comprising at least one activated hydroxyl group [derivative (a-PFPE-OH)];(2) reacting said activated (per)fluoropolyether hydroxyl derivative [derivative (a-PFPE-OH)] with at least one azide salt to yield a functional (per)fluoropolyether derivative comprising at least one azido group [derivative (PFPE-N3)] ; and (3) reacting said functional (per)fluoropolyether derivative comprising at least one azido group [derivative (PFPE-N3)] with a hydrocarbon compound having a terminal alkyne group to yield a functional (per)fluoropolyether derivative comprising at least one triazole group [derivative (PFPE-azole)].
