Low-temperature radiation telomerization of tetrafluoroethylene in hexafluoroisopropanol

Abstract

The kinetics of low temperature (180-270 K) postradiation telomerization of tetrafluoroethylene in hexafluoroisopropanol has been investigated. The efficiency of the process is determined by the initial con centration of the monomer in the solvent and the dose of preliminary irradiation. It has been shown that the telomerization reaction proceeds via the radical mechanism during the devitrification of the system. Active centers that initiate the process and their yield at 77 K have been studied by the ESR technique. Some prop erties of the product telomers have been studied.
