✦ Synopsis

The oxidation of tetrafluoroethylene by molecular oxygen, induced by small amounts of ozone, has been studied by a flow method both in the gas phase and in 1, 1, 2-trichlorotrifluoroethane at 15 ° and atmospheric pressure. The reaction yields, besides the major volatile products (COF2 and CzF, O), a liquid product which has essentially a poly(oxyperfiuoromethylene) structure, (CF20),. The influence of the pressure of the reactants on the irregularities of this chain and on the relative formation rates of the products is discussed in terms of an addition--elimination mechanism, involving fission of most of the peroxidic and C--C bonds of the polymeric chain.
