ABSTRACT:
Neutralization of perfluoropolyethers is accomplished by reacting them with gaseous fluorine in the presence of radiations having a wavelength from 200 to 300 nm. The presence of radiations permits to operate at lower temperatures and with higher reaction rates, and to reach an exhaustive neutralization.
