Abstract
Glow discharge polymerizations of tetrafluoroethylene, perfluoromethylcyclohexane and perfluorotoluene were investigated by infrared spectroscopy and ESCA to clarify the contribution of olefinic double bonds and cyclic structures. The products formed from the three compounds were deposited as filmy polymers containing large amount of fluorine. Their polymeric chains are composed of CF, CF-CFn, CF2 and CF3 groups and have less dependency on chemical structures of the starting compounds. The polymer-forming process involves not only chain reactions via addition reaction to double bonds and via ringopening reaction but also the rupture of C-F bonds and the rearrangement of the ruptured fluorine atoms.
