Abstract
The coating of substrates, particularly polymers and ceramic or metal substrate, for the production of a polar, polymeric coating is conducted by plasma polymerization. The process gas used for this purpose is free from water or water vapor and contains at least one organic compound, in addition to an inorganic gas and/or carbon monoxide and/or carbon dioxide and/or ammonium and/or nitrogen and/or another gas containing nitrogen.

Process which comprises:
- coating substrates with a polar coating, wherein the coating takes place by means of plasma polymerization;
- including the step of employing a water-free process gas which contains at least one substituted hydrocarbon compound with up to a maximum of 8 C-atoms and also an inorganic gas, to produce a coating which is stable in the long term;
- and wherein said coating step further comprises coating at least one of packing materials and substrates for adhesion of composite materials.
