Abstract

The authors have investigated the use of fluorescence spectroscopic measurements as a method for the analysis of yellowing mechanisms in accelerated ageing tests. Two model films with defined composition were used to establish the spectroscopic method. The method was then applied to samples that had undergone accelerated ageing by ozone, thermal and humidity degradation, light exposure and chemical contamination. The use of several different spectroscopic methods allowed to discriminate between optical brightener degradation, yellow stain formation and light scattering. The results were compared to those obtained form spectral densitometer measurements.
