The composition of the gas phase during plasma polymerization of aniline was studied with the use of mass spectrometry; it was shown that at least 20% of aniline is consumed for the formation of secondary products (C

H
2
and HCN). According to solid-state NMR data, the macromolecular chain of polyaniline obtained by plasma polymerization includes both aniline and aliphatic units. The latter units appear as a result of polymerization of the secondary product acetylene.
