PCT No. PCT/DE94/00622 Sec. 371 Date Jun. 17, 1996 Sec. 102(e) Date Jun. 17, 1996 PCT Filed May 31, 1994 PCT Pub. No. WO94/27745 PCT Pub. Date Dec. 8, 1994A method for producing at least a polymer surface layer on at least part of the inner surface of a hollow article that is at least partially of plastic, comprising coating said at least part of the inner surface of the hollow article by establishing a low pressure gas atmosphere within the hollow article, formin a polymerizable plasma within the article by excitation of the gas atmospher within the article by high-frequency electromagnetic energy, and allowing polymerization of the gas atmosphere to take place, whereby a polymerized coating is applied to said part of the inner surface, the gas atmospherre that forms the plasma containing a component that predominantly forms chains at sufficient speed and can be polymerized under the particular plasma conditions, and a component that forms predominantly branching or cross-linking points and can be polymerized under the particular plasma conditions.
