Properties (free‐radical concentration, gas permeabilities, internal stress, and contact angle of water) of plasma polymers of acetylene and of acrylonitrile were investigated as a function of flow rate of monomer in an electrodeless glow discharge. It was found that the monomer flow rate has a strong influence on free‐radical concentration, gas permeabilities, and internal stress but little influence on the contact angle of water. The discharge power has little effect on properties when the full glow is maintained in the reactor. Gas permeabilities decrease with increasing concentration of free radicals in plasma polymers.
