Using peroxide, γ-, and UV-irradiation, freeradical addition reactions of hexafluoropropene to diethers and to 18-crown-6 have been investigated and mono-, di-, and poly-adducts have been obtained. Factors influencing these additions, especially polar characteristics of intermediate radicals, have been elucidated. Adducts of 18-crown-6 retain a capacity to complex to alkali-metal ions.

Ethers and polyethers, that have been modified by grafting multiple hexafluoropropyl units to each system, have been successfully converted to perfluorinated-ethers and -polyethers. Various techniques for further fluorination have been evaluated, including bulk and flow procedures, as well as fluorination of systems adsorbed onto potassium fluoride.
