    Abstract: Continous films are obtained by photopolymerizing on the surface of a substrate a gaseous material selected from hexachlorobutadiene, tetrafluoroethylene, trifluoromonochloroethylene, monofluorotrichloroethylene, hexafluorobutadiene, mixture thereof and acrylonitrile. Preferably ultra-violet light having an effective wave length in the range of 2000 r to 3500 r at a vapour pressure for said gaseous material in the range of 0.1 to 8.0 millimetres is used. Preferably the substrate is cooled during photopolymerization thereby increasing the rate of film formation. An apparatus for carrying out the polymerization is described.

    Abstract: Copolymer films are provided which are made by the surface photopolymerization of vaporous mixture of a diene such as butadiene and a vinyl monomer, for example acrylonitrile. The copolymer films exhibit valuable insulating properties and have a dielectric constant over the range of from about 2.65 to about 5.9.
