Abstract
Postopek za pripravo peroksidnih perfluoropolietrov, ki vsebujejo perfluoroalkilenoksi enote, ki obstajajo iz (CF2-CF2O) in (CF2O), pri čemer tetrafluoroetilen in kisik reagirata v topilu pri temperaturi, ki ne preseže 50 C, v prisotnosti ene ali več spojin z eno ali več vezmi F-X, pri čemer je X izbran iz skupine, ki obstaja iz fluora, kisika in klora. Navedena spojina je zlasti F2 ali organska perhalogenirana alkilna ali alkilenska spojina, ki vsebuje atome fluora ali atome fluora in klora, eno ali več fluoroksi skupin in v danem primeru eno ali več etrskih atomov kisika. Izum se nanaša tudi na produkte, dobljene po postopku v smislu izuma.
