Abstract

Physico-chemical stability of various polymeric materials dedicated to the art market is being discussed as an analytic response under induced artificial ageing. On the basis of an extensive kinetic analysis, a series of correlation could be draw on regard the causes and mechanism of degradation affecting these class of materials by the use of Attenuated Total Reflectance (ATR) – FT-IR measurements and spectrophotometry. Experimental factors, such as the effect of wavelength specificity, on particular case studies, highlights practical aspects that further can be applied for an accurate characterization of the chemical processes involved in the photodegradation of this class of polymeric materials..
