摘要
This study focuses on the identification of photodegradation products of polyurethane foams with enhanced biodegradability, resulting from partial replacement of synthetic by bio-originated and biodegradable polyols during polyurethane synthesis. The tested materials were irradiated by UV-light. Volatile compounds were sorbed during irradiation using SPME, and analyzed by comprehensive orthogonal two-dimensional gas chromatography - mass spectrometry (GCxGC/TOF MS). Semi-volatile compounds were extracted from exposed polyurethane foam by n-hexane and analyzed by gas chromatography - mass spectrometry (GC/MS). A large number of structurally diverse compounds were detected, and most of them were identified. The influence of biodegradable filler on the composition of photodegradation products was also assessed.
