In specialty fluorochemicals ("SFC"), we are one of the few companies in the world capable of utilizing telomerization
The Scotchgard products being withdrawn are electrochemical fluorination (ECF) chemistry-based, while DuPont Teflon and other fluoroprotectant formulas use a process called tetrafluoroethylene (TFE) telomerization
, according to DuPont.
In addition, highly reactive monomers, such as TFE, may be handled more safely as a mixture with C[O.sub.2]. Early work examining the free-radical telomerization
of TFE in supercritical C[O.sub.2] took advantage of the high solubility of the low molecular weight perfluoroalkyl iodide products to prepare these materials homogeneously (Scheme 5).
