This article investigates the deposition of a polymer on an electrode in a glow discharge of alternating current with a frequency of 1 kHz with different procedures for feed and withdrawal of the monomer. The thickness of the coating was determined by microinterferometry with preliminary spraying of aluminium after deposition of the polymeric film on all the substrates. The results indicate that the greatest deviations from the average values of the thickness of the polymer film that was formed in the experiment run were observed in the feeding of the monomer at the level of the bottom of the reaction chamber. The infrared (IR) absorption spectra of the obtained films reveals that the polymer films were identical and differed only in thickness. It is determined that optimization will be achieved when the monomer-feed points are at the maximum distance from the withdrawal points, thereby ensuring the best mixing of the gas within the chamber.
