| 摘要 |
The monomers benzene, toluene, fluorobenzene, chlorobenzene, p-xylene, o-fluorotoluene, m-fluorotoluene, and aniline; also styrene, divinylbenzene, m-trifluoromethyl-styrene, a -methylstyrene, p-chlorostyrene, p-fluorostyrene, phenyl acetylene and phenyl butadiene; also ethylene, acetylene, butadiene, cyclopentadiene, isoprene, propylene, l-butene, vinyl-chloride, vinylidene chloride, vinylidene fluoride, acrylonitrile, trifluorochloroethylene, and tetrafluoroethylene or mixtures thereof are polymerized by subjecting their vapours to an electric glow discharge under vacuum conditions so as to make a very thin evaporated dielectric film in a capacitor. The rate of polymerization can be controlled by using, e.g. nitrogen, helium or argon, to operate the glow discharge with a partial pressure of carrier gas. |
