Process for preparing chlorotrifluoroethylene telomers and new telomers obtained

In the process for preparing chlorotrifluoroethylene telomers by reaction of chlorotrifluoroethylene with CF3 CF or Rx --CF2 OF (wherein Rx may be also a perfluoroalkyl radical having 1 to 10 carbon atoms), the content of telomers with end groups --F is increased or mixtures of telomers containing species with end groups --Cl are obtained by adding F2, according to particular modalities, to the reaction medium.

Process for preparing chlorotrifluoroethylene telomers and telomers obtained thereby

In the process for preparing chlorotrifluoroethylene telomers by reaction of chlorotrifluoroethylene with CF3OF or Rx-CF2OF the yield of telomers with -F end groups is increased or mix-tures of telomers containing species with -Cl end groups may be obtained by adding F2 to the reaction medium under certain operative conditions.

New chlorotrifluoroethylene telomers and process for preparing them

The invention relates to new chlorotrifluoroethylene telomers and to a process for preparing them. Chlorotrifluoroethylene is reacted, at a temperature ranging from -100°C to +40°C, with a fluoroxy compound of formula Rx--CF2OF, wherein Rxrepresents, among others, a perhalogenated alkyl radical containing 1 to 10 carbon atoms. There are obtained telomer mixtures having, among others, the following formulae: Rx-CF2-O-(M)n-F, Rx-CF2-O-(M)n-O-CF2-Rx, Rx-(M)n-F, Rx-(M)n-Rx, Rx-CF2-O-(M)n-Rx, F-(M)n-F, wherein M is CF2CFCl and n ranges from 2 to 20. Most of these telo-mers are new compounds.
