Abstract

Iodine terminated liquid telechelic telomers of chlorotrifluoroethylene (CTFE) containing an average of more than 1 CTFE unit per molecule are novel compounds. The telomers can be prepared by a photochemically initiated reaction between liquified CTFE and either elemental iodine or the telogen ICF.sub.2 CFClI at temperatures below about 50.degree. C.
