Abstract:

A fluorinated polyether is synthesized by 1 reacting perfluoroglutaryl chloride and 1,5-hexafluoropentane diol to provide a fluorinated polyester and 2 converting ester groups of the polyester to ether groups by SF4 reduction. The product obtained is a thermally stable polyether which is particularly useful in providing an elastomeric material for aircraft fuel tank sealants, tire valves, O-rings, hose, gaskets, and the like.
