Abstract

1355595 Tetrafluoroethylene/ethylene terpolymers ASAHI GLASS CO Ltd 6 July 1972 [6 July 1971] 31764/72 Heading C3P Tetrafluoroethylene and ethylene are copolymerized in the presence of 2-30 mole per cent of hexafluoropropylene to give copolymers containing 5 mole per cent or less of hexafluoropropylene units. The polymerization is carried out in saturated fluorinated hydrocarbon solvents, e.g. trichloromonofluoromethane and trichlorotrifluoroethane, using an intitator such as t-butylperoxyisobutyrate or initiating the polymerization by irradiation using, for example, a cobalt-60 source. A mixture of all three monomers is added to the solvent initiator mixture initially and further tetrafluoroethylene and ethylene are added during the course of the reaction.
