The Role of Halogens in the Plasma Polymerization of Hydrocarbons.
Abstract
Vinyl chloride, vinyl fluoride and tetrafluoroethylene were polymerized in a radiofrequency electric glow discharge. It was found that when compared with the unhalogenated simple hydrocarbons, the rates of polymer deposition are in the order of vinyl chloride, acetylene, tetrafluoroethylene, vinyl fluoride, ethylene. This observation can be rationalized by considering the ease with which free radical and unsaturated species can be formed in the plasma. Infrared spectra and structure are compared after plasma and conventional polymerization. The halogenated compounds appear to act as a gas phase catalyst for the plasma polymerization of hydrocarbons. (Modified author abstract)
