A preliminary investigation of polymers prepared by RF and microwave glow discharge techniques is described. The polymer composition structure as revealed by ESCA is discussed and differences are shown to be subtle rather than major. Microwave prepared polymers are more sensitive to the operating co

Abstract
An ESCA investigation has been made of the plasma polymers produced from the isomeric triβ, diβ, and monofluorobenzenes in inductively coupled plasmas. Comparison is drawn with other published data on perfluoroβ, pentafluoroβ, and isomeric tetrafluorobenzenes. The data reveal that extensive molecular rearrangement accompanies polymerization and that proportionately the C:F stoichiometry shows a decrease in fluorine content relative to the monomer in going from perfluoroβ to monofluorobenzene. Internal stress, critical surface tensions, and coefficients of friction are compared for the plasma polymers.
