Treating plastic surfaces useful e.g. for improving adhesion and increasing smear resistance between plastic and friction-reducing low-maintenance layer, comprises carrying out ultraviolet-induced treatment of the surface without water

摘要

Treating plastic surfaces for improving adhesion, comprises carrying out UV-induced treatment of the surface without water. Independent claims are also included for: (1) plastics comprising ring-based polymers and having a functional surface of ring opening products of the aromatic components, where the lower layers remain unchanged, which are obtainable by a UV-treatment at a wavelength of less than 380 nm in the presence of atmospheric gases and ozone; and (2) films or fabrics comprising the plastics.
