Abstract
I HAVE found that the irradiation of tetrafluoroethylene in the presence of mercury vapour by light of wave-length 2536 A. causes a mercury photosensitized reaction. The pressure falls and a white powder is formed. A gas of molecular weight 150 ± 1, b.p. — 33° C, m.p. — 80° C, believed to be hexafluorocyclopropane, molecular weight 150, b.p. — 31° C.1, and a small quantity of a mixture of compounds with higher boiling points have been isolated from the products of the reaction. The white powder has properties similar to those of polytetrafluoroethylene (CF2)n2, the product of the catalysed polymerization of tetrafluoroethylene.
