The present invention relates to anhydrous tetraalkyl pnictogen perfluoroalkoxy salts and a process to produce anhydrous tetraalkyl pnictogen perfluoroalkoxy salts. The process involves contacting a hydrofluoroether and an amine to produce a tetraalkyl pnictogen perfluoroalkoxy salt in the presence of a solvent. The present invention also relates to processes of preparing fluoroalkyl ether acid fluoride polymers using tetraalkyl pnictogen perfluoroalkoxy salt. The present invention further relates to some novel fluorinated alkyl polyether polymers.
