The invention concerns the production of a polymer coating on the inside surface of a hollow plastic article by low-pressure plasma polymerization, the gas atmosphere which forms the plasma being generated at radio frequencies and containing an essentially non-polar gaseous or vapour-form starting material which can be polymerized under the plasma conditions used. The gas atmosphere which forms the coating may c1ontain two or more components which, on the one hand, exhibit a preponderant tendency to chain growth or, on the other hand, a preponderant tendency to the formation of branching on cross-linking points. In addition the gas atmosphere may contain a component which counters the formation of dust.
L'invention concerne l'application d'un revêtement polymère sur la surface intérieure d'un corps creux en matière plastique, par polymérisation au plasma sous basse pression. L'atmosphère gazeuse qui forme le plasma généré à une radiofréquence contient une substance de départ sensiblement non polaire, gazeuse et/ou à l'état de vapeur polymérisable dans les conditions de formation de plasma. L'atmosphère gazeuse de formation de revêtement peut contenir deux ou plusieurs composants qui d'une part tendent surtout à former des chaînes et d'autre part à former des embranchements ou des points de réticulation. Cette atmosphère gazeuse peut en outre contenir un composant qui empêche la formation de poussières.
