Abstract
A telomerization process comprises reacting chlorotrifluoroethylene with bisfluoroxydifluoromethane. The telomerization reaction is conducted in either liquid chlorotrifluoroethylene without a solvent or in solution. The telomers thus formed can optionally be fluorinated by reaction with a suitable fluorinating agent to improve their stability.
