Abstract

Procedimento per separare tra loro le specie non funzionali, mono e bifunzionali in perfluoropoliossialchileni di formula generale XO-RF-Y dove:Rf = catena perfluoropoliossialchilenica comprendente unità monomeriche di formule (CE2 O), (CE2 CF2 O), (CE2 CF2 CF2 O),X, Y uguali o diversi tra loro, sono gruppi terminali non funzionali o contenenti funzioni OH, e/o NH2, con almeno X e Y in parte di tali perfluoropoliossialchileni essendo o contenendo un gruppo -OH, il quale consiste nel sottoporre a cromatografia su colonna tali perfluoropoliossialchileni utilizzando solventi fluorurati non polari, da soli o in miscela con solventi polari, come eluenti.
