Therefore, as a result of surface photo-oxidation the polarity is increased, chromophore groups appeared, and both components have a certain oxidation degree and as a consequence they would be much sensitive to the environmental attack, because the protective PO coating is partially degraded. It can be remarked, increased opacity of the film, the decrease of the film thickness, and for several films the weight loss reached 20%, characteristic for environmentally degradable materials and really they are partially or totally disintegrated and could be assimilated as humic substances. [Pg.505]
