PROCESS FOR THE MANUFACTURE OF FUNCTIONAL PFPE DERIVATIVE

摘要

The invention pertains to a process for the manufacture of a functional (per) fluoropolyether derivative comprising at least one triazole group, said 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)]; 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)].
