“…The value of 6 for a monomer is dependent on the value of p~; however, since the sign of (6-1) does not usually change with the value of p~, the value of 6 can be used as an indication of the behavior of the monomer in a glow discharge. The values of 6 listed in Tables I and I1 are selected from the nearest value of p~ to a common value of 40 fi Hg.…”

SynopsisThe rates of polymer deposition from various olefinic monomers in an electrodeless glow discharge were studied. The previously found empirical relationship (with styrene in part I) between the rate of polymer deposition R, the monomer pressure PN, and gas pressure p , in a steady-state flow system (i.e., R = a(pai)* [l + b(p,)], R being nearly independent of the discharge power) was also found with all monomers investigated. (The effect of gas was examined with nitrogen in this study.) However, it was found that the polymer deposition is controlled by the monomer flow rate and RO (in pure monomer flow) is proportional to the flow rate of monomer F , (based on the weight);i.e., RO = kF,, where k is a characteristic rate constant of the polymerization. Olefinic monomers can be generally classified into two major groups, i.e., type A monomers which predominantly polymerize, and type B monomers which decompose in a glow discharge. Type B monomers have smaller values of a and k compared to type A monomers. The values of a and k for type A monomers both increase with increasing molecular weight of the monomer. The values of k for all monomers investigated are within roughly an order of magnitude, indicating that the reactivity levels of monomers are very similar in a glow discharge polymerization.

“…There is evidence that the propagation step involves the reaction of radicals with monomers adsorbed on the electrodes. Fally et al [4] studied plasma deposited AAl films by XPS and high resolution electron energy loss spectroscopy. They concluded that oxygen-rich polymers can be obtained from the unsaturated monomers at a low power.…”

Poly(allyl alcohol) films with a thickness of about 150 nm were deposited by pulse plasma polymerization onto different substrates (inorganic and organic). The structure/property relationships of these samples were studied in dependence on the duty cycle (DC) of the plasma by a broad combination of different techniques and probes. For the first time volume sensitive methods (FTIR and dielectric spectroscopy) are combined with surface analytics by employing XPS for that system. FTIR spectroscopy gives qualitatively the same dependence of the concentration of the OH groups on DC like XPS. The observed differences are discussed considering the different analytical depths of both the methods. The dielectric measurements show that the plasma deposited films are not thermally stable but undergo a post plasma chemical reaction during heating. The results obtained by dielectric spectroscopy are discussed in detail with the data from FTIR and XPS measurements.
