Bond-structure of hydrocarbon and density of polar groups at the surface region of argon and oxygen plasma-treated polyethylene (Ar-PE, 02-PE) were investigated by means of the XPS 1 s and valence band spectra. In case of An-PE, branching and cross-linking hydrocarbo n units occur first, then reaction of radical survived with oxygen and/or nitrogen results in polar groups at the film surface. In case of 02-PE, oxidation of the polymer film is prior to branching and cross-linking.
