1933Jrnl. Amer. Chem. Soc. LV. 3177 There is good evidence that tetrafluoroethylene is produced in small quantities. 1946Sci. News IV. 63 Polymerisation of tetrafluorethylene..yields heat-resistant, chemically inert solids, which can be moulded into any desired shape. 1958Times Rev. Industry Feb. 81/2 A rather typical example of what can be achieved with fluorocarbons is the polymerization of tetrafluoroethylene to yield a commercial plastic. 1973Materials & Technol. VI. 544 The monomer tetrafluoroethylene is obtained by pyrolysis from CHFCl2 (..that is, the refrigerants Freon-22 and Genetron-141). |
