Summary

  1. 1.

    By the telomerization of tetrafluoroethylene with 1,2-dichlorotrifluoroiodoethane a series of dichloropolyfluoroiodoalkanes CF2ClCFCl(CF2CF2)nI (n=1 2m,3, and 4) were prepared.

     
  2. 2.

    Under the action of zinc the resulting dichloropolyfluoroiodoalkanes were converted into the corresponding tetrachloropolyfluoroalkanes and further into perfluoro α,ω-diolefons CF2=CF(CF2)nCF=CF2 (n=2, 3, 4, and 6).

     
  3. 3.

    Oxidation of the perfluoro α.ω-diolefins gave perfluoro dicarboxylic acids HOOC(CF2CF2nCOOH (n=2, 3, 4, and 6).

     
  4. 4.

    By the heterophase condensation of perfluoroadipoyl and of perfluorosebacoyl chloride with 1,6-hexanediamine, fluorinated polyamides were prepared.
