Abstract

Telomers of formula CF3O - (CFCl - CF2)n - X where n is 1-10 and X is F or OCF3, are formed by reacting chlorotrifluoroethylene with fluoroxytrifluoromethane or bisfluoroxydifluoromethane. The telomerization reaction is conducted either in liquid chlorotrifluoroethylene without a solvent or in solution. The telomers thus formed can optionally befluorinated (e.g. with ClF3) to improve their stability by replacing some or all of the chlorine by fluorine.
