✦ Synopsis
The polymerization of a group of vinyl monomers in a radio-frequency glow discharge has been studied with particular reference to the potential application as a gas-phase surface coating process. Using capacitive coupling of power into the monomer gas, rates of polymer deposition have been measured as a function of pressure, current density and electrode surface temperature. An increase in deposition rate with decreasing electrode temperature (other parameters constant) has been observed for all the monomers studied. A mechanism of polymer formation is suggested, positive ions from the gas phase reacting on the electrode surface with adsorbed monomer molecules.
